Many readers are creatures of habit. They read Historical Fiction or Fantasy, Science Fiction or Mystery, but don’t expect them to cross genre. That other genre is not what they read. One aim of this article it to present, from the point of view (POV) of a Science Fiction reader, some Science Fiction and Mystery/Detective crossover novels so that teacher-librarians might tempt some students to open new passages in their reading patterns. This also opens up an opportunity for other Bookmark readers, who come from the POV of Mystery/Detective readers, to identify some novels with Science Fiction elements to encourage more genre blending.
One of Canada’s best Science Fiction writers is Robert Sawyer. He has won the Aurora, Hugo and Nebula awards for Science Fiction. He states that: "Science fiction and mystery have a great deal in common. Both prize the intellectual process of puzzle solving, and both require stories to be plausible and hinge on the way things really do work."
Crossover novels have been around for a long time. It could be argued that, when they were published, Arthur Conan Doyle’s Sherlock Holmes novels and some of the Hardy Boys and Nancy Drew novels, for a younger audience, with their reference to then cutting edge technologies combined strong elements of Mystery and Science Fiction. In recent years, these kinds of crossover novels have been, perhaps, less common. Fortunately for me, over the last few years I’ve read a stream of crossover novels and begun to ask myself, "What else is out there?"
Some of the mixed genre novels I’ve read include: Halting State by Charles Stross, The Yiddish Policeman’s Union (which won the Hugo and Nebula awards for 2009) by Michael Chabon, The Automatic Detective by A. Lee Martinez, Necopath by Eric Brown, The Prefect by Alastair Reynolds, Third Claw of God (from The Andrea Cort series) by Adam-Troy Castro, Time Machines Repaired While-U-Wait by K.A. Bedford, Farthing by Jo Walton, and End of the World Blues by Jon Courtenay Grimwood.
From these books I would strongly recommend these three novels: although all are worth consideration.
Halting State, by Stross, is set in the near future in Edinburgh, Scotland. It blends an edgy techno theme with near future geopolitical elements, from a Thomas Friedman style ‘flat world’ in which India and China present grave threats. This might attract both techno readers and those interested in geopolitical thrillers, such as the novels by Tom Clancy and Dan Brown.
The Yiddish Policeman’s Union features the considerable talents of Michael Chabon who has also published contemporary and Historical Fiction novels. Set in Sitka, Alaska this novel is in the style of some of the alternate histories written by Harry Turtledove and S. M. Sterling. In this novel, Jews have been settled after the Second World War, by reluctant agents of the American Government on leased land in Sitka rather than in Israel, which remains under Arab control. With the lease soon to run out, a recent murder can either be pursued or dropped. In the best tradition of the detective novel, Meyer Landsman sets out to solve what will likely be his last case as a police officer. This is a highly recommended read.
The Automatic Detective by A. Lee Martinez is a humorous novel. Mack Megaton drives a Bluestar cab, but would rather be a classical Sam Spade style private investigator. A major problem he faces is that he is a very large robot—actually a modified military robot designed to take over the world by force—but sidetracked into driving a cab. But a robot’s gotta do what a robot’s gotta do. With the help of his sidekicks—a genetically modified and cognitively enhanced gorilla named Jung and the voluptuous, and rich, Lucia Napier, Mack sets off to solve the case of a missing person. Martinez upends every cliché identified with detective novels with twists and turns reminiscent of the works of Terry Pratchett and Douglas Adams when they set tradition on its head with their quirky and funny Fantasy and Science Fiction writings.
Another form of cross-over writing comes from the blending of Vampire, Mystery and Science Fiction themes. Jes Battis with Night Child, merges CSI style detective themes with the advanced technology found in Science Fiction. Tanya Huff with Smoke and Mirrors, provides an example of this kind of genre fusion.
James Patterson’s Maximum Ride Series, Anthony Horowitz’s Alex Rider Series, and Eoin Colfer’s Artemis Fowl Series all have elements that allow them to be described as crossing over between Science Fiction and Mystery. Certainly, many students who have enjoyed the different writings of these authors and who are looking for additional suggestions from teacher-librarians might consider dipping their toes into either the more traditional Science Fiction or Mystery genre.
Libraries may already have some crossover material in their collections. Kiln People by David Brin, Carlucci by Richard Paul Russo, the Eve Dallas novels by J.D Robb, Do Androids Dream of Electonic Sheep (which was made into the movie Bladerunner) by Philip K. Dick, Dirk Gently’s Holistic Detective Agency by Douglas Adams, and The I, Robot series by Isaac Asimov are all examples of crossover novels.
My bias as a fan of Science Fiction shows throughout this article. What is needed is for another Bookmark reader to lay out the path for Mystery and Science Fiction novels that can be used to cross these genre from the other direction. I’m looking forward to your suggestions!
As with every article, here are the nominated books for some of the other yearly Science Fiction and Fantasy awards that are, perhaps, not as well known as the Auroras, Nebulas, and Hugos. Included are the nominated novels for the Sunburst Awards for Canadian Science Fiction and Fantasy, the British Science Fiction and, separately awarded, British Fantasy Awards, and the Golden Duck Awards, with an emphasis on Science Fiction for K-12 students.
The eBook Challenge

In spite of media hype, libraries will not disappear in the next few years. But eBooks and eBook Readers will challenge the traditional roles and practices of K-12 libraries and the staff who work there. Librarians need to know what eBooks are, how they may evolve and what eBook Readers are and how this technology may develop. As important as it may be to stay on top of technological developments, teacher-librarians also need to anticipate some changes in practice that will be required as eBooks and their readers show up in schools.
What are eBooks?
eBooks are books in a digital form. eBooks have been around for more than a decade. The availability of eBooks, like audio books, has been a source of interest for teacher-librarians, but their presence has not yet changed daily operations. The continued development of devices that ‘read’ eBooks, eBook Readers and changes in the sophistication of eBooks themselves will change that.
The first generation of eBooks—novels and some non-fiction material—were one-dimensional: they lacked sophistication and intelligent operations. The textual material, that could be found in a traditional novel was presented as a plain computer file. You could not, for example, pop up a map or photos to enrich a story. Computers, both desktop and laptop, were the original ‘market’ for most of these eBooks. Many of the original eBooks were either demonstration projects–not likely to have a large market–or material that was out of copyright, from groups such as Project Gutenberg.
Since almost all contemporary books are, in publication form, computer files, some publishers also sold copies of novels in a digital format. At the same time as these fiction and non-fiction books were being marketed, textbook and magazine publishers also began to offer their materials in a digital format such as a PDF file. In a school setting, requests for these formats often came from the parents and teachers working with students facing a variety of learning challenges.
There have been a number of problems with eBooks. Essentially these problems break down into two main categories: format issues and ownership. As with most new technologies, format[1] has been, and to some extent still is, an issue. Some eBooks worked on some computers and not on others. Some school computers had the software needed to read an eBook and some didn’t. Proprietary, and thus access limiting, formats were initially the norm. Recently, more widely available formats such as PDF (from Adobe) and ePub have become common. However, format challenges continue to plague the acceptance of eBooks. Some publishers have begun to deal with these concerns by providing their works in multiple formats. However, just as it took more than a decade to work through the VHS vs. Beta videotape and other format wars[2], some challenges remain. Without regard to the eventual outcome, librarians, support staff, and district technicians will have to gain some level of sophistication in dealing with format issues in order to provide materials to students and teachers in a digital format.
A second major problem with eBooks has been ownership. A purchase of a traditional book transfers ownership of that copy of a book and the rights to resell it to the purchaser. Intellectual copyright is retained by author and publisher. This works well because of the challenges linked to copyright theft—especially with novels. Digital resources present a very different problem. The electronic transfer of files is simple and so, threatening to authors and publishers. Some early eBooks tried to address this with limits around Digital Rights Management: DRM. Essentially, ‘buyers’ leased an eBook for a fixed term (even though they might not have fully understood that). At the end of that term their ability to access the eBook was extinguished. They didn’t own the book. They couldn’t, in some cases, even transfer the book to another computer (desktop to laptop). They couldn’t ‘lend’ the book to a friend. In many cases they couldn’t print pages from a book: such as a map or chart referenced throughout a chapter in that work. Public libraries, such as the Vancouver Island Regional Library: VIRL, use specialized software to help manage eBook distribution and to retain the digital rights for an author/publisher. Users must download software, provided by VIRL, onto their computer and then can access a book for a ‘term certain’ period (typically 21 days for a novel) before the file becomes unusable.
Limits on ownership of an electronic copy of a book cause other problems. Will readers want to purchase books that they can’t re-read as they see fit over years and decades? (Ask readers of the Lord of the Rings series or Robert Munsch books how many times they have read those books.) Some book owners make way for new material by selling their ‘read’ books to used book stores or by donating books to charities. eBook ownership, as it moves past the restrictions imposed by DRM schemes, will certainly raise issues related to the transfer of that ownership and the rights of the copyright holders. Libraries, with their special responsibility to not violate copyright, will have to deal with these issues. This will be especially true with eTextbooks as they reach the end of a use cycle.[3]
In the last year or so, as more eBook readers have come onto the market, textbook publishers have found new ways to market expensive College and University materials for traditional computers and eBook Readers. New companies, such as CourseSmart, provide students with a way to lease their textbooks as a kind of ‘subscription’.[4] ‘Subscriptions’ typically last for a semester or academic year and cost 50-60% of a print copy. CourseSmart materials are available either via an online account or to a specific, and "non-transferable" computer (a laptop for example) or to an eBook Reader or smart phone such as the Blackberry Storm, Apple iPhone or Palm Pre. Some eTextbooks allow computer versions of their material to print pages or study materials or workbook questions; a function not always allowed, or possible, in other eBook formats. These kinds of ownership add more complexity to issues of ownership.
eBooks will evolve over the next few years. Some eBooks will continue to be presented in a one-dimensional format. Novels might remain largely one-dimensional. Non-fiction material, newspapers and magazines and eTextbooks must evolve if they are to retain value for both the user and seller. With 50 million K-12 students in the U.S. and another 18 million students at the college level, the textbook market is significant and competitive. Cash strapped governments at the K-12 level, such as California, are seriously looking at eTextbooks as a way to save money.
ARC BC: Accessible Resource Centre British Columbia, from SET BC, is the K-12 educational body with the most experience with digital resources. Established a little over a year ago, it has begun to collect and distribute digital resources to qualified students throughout the province. ARC BC also cooperates with a number of similar bodies and agencies across Canada. The librarians at ARC BC and the digital librarians associated with public libraries in BC have key information and experience in handling, cataloguing, and the distribution of digital resources that can be tapped into by the K-12 system.
eTextbook 2
Librarians can anticipate a fairly rapid evolution of eTextbooks. Rather than continuing to be one-dimensional, they will become more sophisticated. Additional material, which takes full advantage of the technology, can be added with minor increases in the file size of an eTextbook. eTextbook 2 could contain, for example, a fast slide show of a beating heart or of an engine working—and so give the illusion of animation—without too much difficulty. eTextbook 2 could contain greatly increased information in the form of glossaries, additional exercises, and even, and this is where teachers might be interested, alternate formats that support different reading and skill levels. The SFU Museum site "A Journey to a New Land" and the University of Michigan site "Windows to the Universe: The Earth’s Moon" provide Universal Design for Learning: UDL examples of content tailored to users.
Independent suppliers of second edition eTextbooks might take this customization a step farther. It is technically possible for a teacher to select specific chapters from different textbooks in order to compliment their instruction. This could be done, for example, with the McGraw-Hill Ryerson and Nelson Science 7 textbooks. Both address the same provincial learning outcomes. A teacher might prefer the presentation of the Earth Science unit from one publisher and the Chemistry Unit from another. Independent textbook suppliers, working with both publishers and a school, might sell, on a yearly basis or longer, the rights to different parts of different textbooks to the same school. (Publishers might find themselves in a situation where they need to update their textbooks on a regular basis in order to be the ‘current’ supplier. This might have the beneficial effect of allowing mistakes in textbooks to be corrected and new information added with each new sub-edition.)
eTextbook 3
Second edition eTextbooks are also likely to be quickly replaced by multi-dimensional textbooks: eTextbook 3. Tailored to a student and their teacher, in terms of their reading skills, learning style, teaching style and other preferences, these books can and would be updatable on an ongoing basis. A student showing mastery of a math topic, might move, in their eTextbook, to a section expanding the breadth or depth of their knowledge, whilst a student struggling with a topic might receive additional help that compliments their needs and strengths. Advances in a topic, such as Science, could be incorporated into eTextbook 3s on an ongoing basis. In mid-September 2009, McGraw-Hill announced its version of an eTextbook 3 that allows students to capture audio and video copies of notes and link them to specific sections of the textbook, take quizzes and receive grades and suggestions for further work, and provide teachers with course management tools.
Teachers might find that this kind of smart eTextbook, which need not be platform or publisher dependant, could act as a powerful synthesising agent and knowledge launch pad. This might bring value to a teaching resource: the traditional textbook, which is frequently underutilized because of its one-dimensional, and quickly outdated, format. The combination of an adaptable primary information resource with the powerful skill sets that teachers bring to their classroom might result in some significant changes to education.
What are eBook Readers?
eBook Readers are electronic devices specifically designed to read eBooks. Typically, they show material using so-called e-paper which allows text to be read, usually in black and white, much like a paper book in direct sunlight. Text is stable on the screen and is not constantly refreshed. As a result, battery life can extend for up to a week compared to hours for most laptops. (Computer-based PDF readers and programs such as the Microsoft Reader can read eBooks on those machines.)
Most manufacturers separate eBook readers into 5" and 6" sizes and bigger devices.[5] Smaller devices, the 5" and 6" readers, are designed primarily for paperback and trade paperback publications. eBook Readers have been available for about a decade, but have only slowly been accepted by large numbers of users. Part of the acceptance challenge they have faced has revolved around incompatible formats, limited connectivity, limited tools (so that all a reader could do was show text) and the ownership issues linked to Digital Rights: DRM. The November 2007 launch of the Amazon Kindle provided a spur to the acceptance of eBook Readers.
In the fall and winter of 2009 a number of larger eBook Readers will appear. These include the Asus Eee Reader, the Amazon KindleDX, the PlasticLogic reader and Sony’s Daily Edition. These devices can all present larger books, such as textbooks as well as magazines and newspapers. Advances in technology continue at a rapid pace. The ASUS device, for example, is a clamshell style which will reportedly have two screens (see photo at beginning of this article) and display colour text. The two screens will allow it to act like a traditional textbook. The screens can be used to display different information: a textbook page, for example, and a supportively designed web page. The Plastic Logic screen is about the size of a MacLean’s magazine and has the same weight as a Seventeen or Transworld Skateboarding magazine and a flexible plastic screen that might provide considerable wear and tear for student users.
Built-in and add-on memory cards allow these devices to easily hold all of the textbooks required in K-12 schools and still have room for additional material. Each wave of readers has had more technological sophistication. Models out this fall reportedly include tools for user annotation/note taking, limited printing, and the ability to play, through an earphone jack, stored music and audio books as MP3 files. The ASSU device, raising the stakes, is reported to have a microphone, built in speakers, and a webcam that, via its wireless connection, will allow users to use Skype and similar software. Most eBook Readers can access resources wirelessly using a combination of Internet and cell phone technology. (Although this connectivity is still limited in Canada as users of Kindle devices can attest.)
Newspapers, such as USA Today and the Financial Times, which will be available on the PlasticLogic Device and magazines, such as Time and the Economist, already available on the Kindle, will be pushing for the kind of technological convergence which brings users to these larger sized products and keeps them there. A larger screen will allow publishers to integrate advertising into their presentations in ways that attract readers, rather than just taking up critical screen space. The more users can rely on one device, the more likely that device will be adopted. Increased technology convergence seems likely with each new model. Thus, an eBook Reader that allows you to read a book, view a GPS map, answer a phone call (via Skype), read and respond to an email, and listen to music or an audio book, and dictate notes for eventual conversion via Speech to Text software seems likely in the near future and represents significant challenges for the present manufacturers of some of these separate devices. The search is on for the value added device that reduces the number of gadgets in our lives. Manufacturers are all looking for a Goldilocks solution.
Challenges for K-12 Libraries
Like many new software programs and electronic devices the promises are many. As these two separate technologies continue to advance, greater and greater expectations will be placed on librarians and libraries. These challenges can be largely summarized in four areas: ethical issues, library planning and operations, content problems, and mechanical problems.
Ethical issues abound in the eWorld. Theft of copyright material is a challenge facing the music industry and so it will be for publishers. The fact that eBooks and eBook Readers are not likely to appear in large numbers for the 2009-2010 year means that teacher-librarians have the benefit of some time to begin to sort out ethical issues. While copyright issues are important, social justice issues are, perhaps, more critical. So the questions begin with: How do we ensure equity, what role do librarians (and our technical advisors) have in ensuring that all school distributed material is legal (that we have purchased what we are distributing), what role do we have to play in ensuring that school devices present, at least in the main memory chips (provided within the machine), only legally purchased material: eBooks, eTextbooks, audio books and music, newspapers, magazines, where do our ethical responsibilities end, and what powers, if any, do we have to enforce our ethical choices on school supplied machines being used by students. (Can we require them to delete stolen files from eBook Readers we supply?)
Planning and operational challenges come in terms of: who, what, how, and money. Who within a library, or school system, is going to act as the initially responsible agent? What service, or services, will a school library provide its users. Will they, for example, be responsible for just eBooks? Will eTextbooks be added on? Will they provide eReaders to staff and students? (All staff and students?) Whom will they be responsible for dealing with: publishers, content suppliers, and/or device suppliers? How will they deal with the simple mechanism of ‘signing out’ an eBook or an eBook Reader? Where will the money come from and are there assurances that this will be built into the budget of the Education System, a School Board, and a specific Library?
Resource management for eBooks and eTextbooks will be a second level of challenge for librarians. They will need to know what has been selected (and by whom and from what budget), what they have within their eCollection, in what format (a physical disk or a downloadable file), the number of copies of a resource (from one or two for a novel to potentially hundreds for an eTextbook), the mechanism needed to purchase (lease) more copies, how to deal with Inter-Library Loans (ILL), and how to dispose of surplus to need copies.
Mechanical problems will challenge libraries from the day the first eReader comes into their school. Questions here include: where is the money for this coming from, who is the supplier, who is responsible for minor challenges, such as battery recharges and "I forgot my eReader at home. Can I borrow another one?" to who is going to fix eReaders devices, update their firmware and software and the software on school computers that reads eBooks and eTextbooks. Because eReaders can hold a significant amount of material, another technical question will revolve around where, on a school managed device, the eTextbooks reside. (Will these be near the core and not easily discarded by a user who feels that their collection of 1950s Mad Magazines is more important than their Science textbook or else a student may report that their "eTextbook didn’t work and couldn’t do their homework.")
Challenges for Providers
Much of this article deals with the potential of eBooks and eBook Readers. An August 26, 2009 webinar presented some very interesting information on how these technologies are doing on at least one college campus. In this webinar, titled "E-Readers and E-Textbooks: Current Reality and Future Possibilities" by Jon T. Rickman and Roger Von Holzen from Northwest Missouri State University, the authors PowerPoint presentation reviewed that school’s decision to invest in both eBooks and eBook Readers for a number of faculty and students during the 2008-2009 academic year.
They found that there was a learning curve for which they needed to provide training in order for students and faculty to make effective use of the technology. Users wanted eBooks/eTextbooks and either the readers or software to support keyword searches and note-taking. These researchers also found that eReaders captured attention, but did not keep it unless support features, such as "search and annotation", were built into them. (This supports the need for devices that provide convergence to the multi-tasking expectations of users.). Users found that some subject-based eTextbooks were different from others. eTextbooks, with dense columns of information in tables or charts, often did not display this information as well as text-based material. (Thus, the need for eTextbook 2 and 3.)
Students and faculty, according to Rickman and Von Holzen, found that, computer-based software readers provided more utility. On desktop and laptop computers, students could make more use of the material because of built-in search and note-taking functions, but these machines also allowed them to customize page views and to share searchable notes. (And, of course, students could multi-task and listen to music, e-mail, and be a part of their social network while on their own computer.)
Technical issues, while a focus of this article, once resolved behind the scenes and before the experiment began, were negligible. The researchers reported that:
* "The delivery of eTextbooks to students via their notebook computers was a simple and very efficient process
* Students were able to complete the downloading of eTextbooks with little assistance from university support staff
* Several publishers were able to provide enhanced eTextbooks with quizzes and shared notes
* The need for standardized reading features appeared useful as some students used multiple eTextbooks
* Some eTextbook features, if used in the classroom, need additional Wi-Fi connectivity"
In summary, based on their experience after one year, students at Northwest Missouri State University found ways to use, and maybe embrace, most eBooks, but eBook Readers still had a way to go.
Another challenge for publishers and manufacturers should come in the form of the minimum expectations by the Public School System, for eBooks and eBook Readers in terms of Social Justice. Several expectations must be met. First and foremost is that all eBooks must meet the different needs of students with learning challenges. Thus, an eBook or eBook Reader, without meeting the Text to Speech: TTS needs of students facing learning challenges should not be considered. Other tools supporting learning adaptations for students facing visual challenges—such as changeable text size, font, colour/shading (for colour blindness)—must also be built in at a fundamental level, for a product or device to be considered. With 50 million users, the system has the purchasing muscle to identify and set minimal standards and the system should not forget their responsibilities for meeting these student needs in a rush to new technologies. A second minimal expectation must deal with the intra-system transferability of materials. At present, some computer software is only usable within one school in a district. That must not be allowed to continue with eBooks and their readers, which should be seen as always being open to meet the intra school needs within a purchasing district.
eBooks are here to stay. We should expect that, as they learn from their experiences, publishers will quickly move their materials from the one-dimensional approach that mirrors traditional print books to more sophisticated and multi-dimensional resources. eBook Readers, provided they pass the Goldilocks test and provide for individualization, are likely to become more commonly used. Teacher-librarians have some time to begin to grapple with the issues associated with these technologies. However, in these tough economic times, where governments are looking to save money, and where media reports of the impact of eBooks may add pressure on authorities to act, Teacher-librarians need to begin to sort out their answers to the challenging questions around planning, resource management, hardware/software problems, and ethics. Two strong themes running through all of our responses will be: Do I know enough? and where will the money come from?
