An e-book (also: eBook, ebook) is an electronic (or digital) version of a book. The term is used ambiguously both to refer to either an individual work in a digital format, or a hardware device used to read books in digital format. Some users deprecate the second meaning in favor of the more precise "e-book device". However the term interplay works out colloquially in the long run, e-books are an emerging and rapidly changing technology, and since at least 2004 have included newer experimental online magazines, pioneered in part by Baen's Books in their release of the first Grantville Gazette.
The term e-text is often used synonymously with the term e-book, and is also used for the more limited case of data in ASCII text format excluding books in proprietary file formats. An exception to this rule is the academic e-text, which commonly includes components such as facsimile images, apparatus criticus, and scholarly commentary on the work from one or more editors specially qualified to edit the author or work in question.
An e-book is commonly bundled by a publisher for distribution (as an e-book, an ezine, or an Internet newspaper), whereas e-text is distributed in plain text, or in the case of academic works, in the form of discrete media such as compact discs. Metadata relating to the text are sometimes included with etext (though it appears more frequently with e-book). Metadata commonly include details about author, title, publisher, and copyright date; less common are details regarding language, genre, relevant copyright conventions, etc.
E-guides were first introduced on eBay by a seller with the user name "ColidgeGraduit". They are usually in Microsoft Word or plain text files, and are usually short guides in a step-by-step format. This simple format is easily prone to plagiarism, since almost anybody can just save the file to their computer then resend it to someone else claiming it as their own. Security measures are being introduced in order to secure simple Microsoft Word documents from being edited by the recipients.
eGuide as a document description was first introduced by the eToolcase in early 2001. The idea is that it provides a decriptive guide to complete any task. The eGuide provides exactly that, a guide in electronic format. Normally concise and to the point, may be any length and contain pertinent guides to achive the goal of the content.
A standard formalized by Microsoft Corporation for specifying formatting of documents. RTF files are actually ASCII files with special commands to indicate formatting information, such as fonts and margins.
HTML is the markup language used for most web pages. E-books using HTML can be read using a standard browser (e.g., Mozilla, Firefox, or Microsoft Internet Explorer), with no need for special equipment.
OPF is an xml-based e-book format created by E-Book Systems. E-books created in this format are also known as FlipBooks as the viewing software presents the book in a 3D flipping format. There is an on-going project to make the OPF readable using a standard browser (e.g., Mozilla, Firefox, or Microsoft Internet Explorer), with no need for special equipment. Currently it requires the viewing client for the full Flipping experience.
FictionBook is a popular XML-based e-book format, supported by free readers such as Haali Reader and FBReader. See http://haali.cs.msu.ru/pocketpc/FictionBook_description.html
Plucker is a free e-book reader application with its own associated file format and software to automatically generate plucker files from HTML files, web sites or RSS feeds. The format is a compressed HTML archive, somewhat like Microsoft's CHM.
CHM format is a proprietary format based on HTML. Multiple pages and embedded graphics are distributed along with proprietary metadata as a single compressed file. In contrast, in HTML, a site consists of multiple html files and associated image files in standardized formats.
A file format created by Adobe Systems, initially to provide a standard form for storing and editing printed publishable documents. Because documents in .pdf format can easily be seen and printed by users on a variety of computer and platform types, they are very common on the World Wide Web. But since they are designed to reproduce page images, and the text cannot be re-flowed to fit the screen width, PDF files designed for printing on standard paper sizes are hard to view on screens with limited size or resolution.
NOTE: Adobe have addressed the issue of people viewing PDF files on smaller screens as are found on PDAs (Personal Digital Assistants). Adobe's Acrobat Reader for the PDA now has a re-flow facility. Unfortunately, certain settings need to be in place at the time the PDF document is created for it to be re-flow-able, which means many existing PDF documents won't benefit from this new feature. These settings can be found at Reflow the contents of Adobe PDF documents: Tutorial.
PDF files are created mainly using Adobe Acrobat, but Acrobat Capture and other Adobe products also support their creation, as do third-party products such as PDFCreator, OpenOffice.org, and FOP. Acrobat Reader (now simply called Adobe Reader) is Adobe's product used to view PDF files. PDF files typically contain product manuals, brochures, magazine articles, or flyers as they can embed fonts, images, and other documents. A PDF file contains one or more page images, each of which you can zoom in on or out from. The PDF format can include interactive elements such as buttons for forms entry and for triggering sound and Quicktime or AVI movies. Acrobat PDF files are optimized for the Web by rendering text before graphic images and hypertext links. Adobe's PDF-like e-book format is incorporated into their reader.
PostScript is a page description language used primarily in the electronic and desktop publishing areas for describing the contents of a printed page in a higher level than the actual output bitmap.
DjVu is a file format that has been long in obscurity, but that is starting to surface now that free tools to manipulate the files are available.
DjVu is a format that particularly excels in storing scanned images. There are even advanced compressors especially specializing in low-color images, such as text documents. Individual files may contain single pages, or they can be collections of multiple pages.
The images are divided in separate layers (such as multi-color, low-resolution, lossily-compressed background layer, and few-colors, high-resolution, tightly-compressed foreground layer), each compressed in best applicable method. The files are also designed to decompress very fast, even faster than vector-based formats.
The advantage of DjVu is that it is possible to take a high-resolution scan (300-400 DPI), good enough for both on-screen and printing, and store it very efficiently. Several dozens of 300 DPI black-and-white scans can be stored in less than a megabyte.
The MS reader uses patented ClearType® display technology. Navigation works with a keyboard, mouse, stylus, or through electronic bookmarks. The Catalogue Library records reader books in a personalized "home page". A user can add annotations and notes to any page, create large-print e-books with a single command, or create free-form drawings in the reader pages. A built-in dictionary allows the user to look up words.
eReader is a program for viewing Palm Digital Media electronic books. Versions are available for PalmOS, PocketPC, Symbian OS, Windows, and Macintosh. The reader shows text one page at a time as paper books do. eReader supports embedded hyperlinks and images. Most eReader formatted books are encrypted, with the key being the purchaser's full name and credit card number.
The Mobipocket Reader has a home page library. Readers can add blank pages in any part of a book and add free-hand drawings. Annotations — highlights, bookmarks, notes, and drawings — can be applied, organized, and recalled from a single location. Mobipocket Reader has electronic bookmarks, appearing in the page margins. Dictionaries allow users to look up definitions through a built-in lookup function.
The reader has a full screen mode for reading and has Microsoft ClearType® support. On Palm OS, readers can use sub-pixel rendering with the MobiType® font. Mobipocket Reader runs on many PDA types (including Palm OS, Pocket PC and Windows CE, Tablet PC, Casio BE-300, Psion, Symbian OS Smartphones, Franklin eBookMan) and on Windows 2000/XP. Mobipocket products do not allow reading on Linux, Macintosh or other operating systems. These systems may be used only as a conduit to a PDA.
The Mobipocket e-book format based on the Open eBook standard using XHTML can include JavaScript and frames. It also supports native SQL queries to be used with embedded databases.
The Mobipocket encryption system is not a password based system. Its DRM relies on the PDA hardware serial number.
A free e-book of the German Wikipedia has been published in Mobipocket format; see *.
ExeBook is a compiler that produces an e-book file that, when executed, produces a simulated book onscreen, complete with page texture. The etext is encrypted as graphic images so that automatic text copying is very difficult. The fear of exe files picking up viruses, however, is hampering its acceptance.
DesktopAuthor is an electronic publishing suite that allows creation of digital web books with virtual turning pages. Digital web books of any publication type can be written in this format, including brochures, e-books, digital photo albums, e-cards, digital diaries, online resumes, quizzes, exams, tests, forms and surveys. DesktopAuthor packages the e-book into a ".dnl" or ".exe" book. Each can be a single, plain stand-alone executable file which does not require any other programs to view it. DNL files can be viewed inside a web browser or stand-alone via the DNL Reader.
All systems running the Newton operating system (the most common include the Newton MessagePads, eMates, Siemens Secretary Stations, Motorola Marcos, Digital Ocean Seahorses and Tarpons) have built-in support for viewing Newton books. The Newton package format was released to the public by Newton, Inc. prior to that company's absorption into Apple Computer. The format is thus arguably open and various people have written readers for it (writing a Newton book converter has even been assigned as a university-level class project).
Newton books have no support for DRM or encryption. They do support internal links, potentially multiple tables of contents and indexes, embedded grayscale images, and even some scripting capability (for example, it's possible to make a book in which the reader can influence the outcome).*
Apabi is a format deviced by Founder Electronics. It is a popular format for Chinese e-books. It can be read using the Apabi Reader software, and produced using Apabi Publisher. Both .xeb and .ceb files are encoded binary files. The Iliad e-book device includes an Apabi 'viewer'.
Perhaps the most illustrative of how rapidly evolving and hotly contested the e-book format and digital data war is the evolving position held by Speculative fiction publisher Baens Books. Baen's began by surveying the field of e-book formats available in 1999, and decided to publish using cryptographically keyed downloads in several of the more common and useful formats, including the ubiquitous Rich Text Format output compatible with Microsoft WORD and Microsoft Windows utility program Write.exe (WordPad).
Subsequently, in early 2004 they experimented with an online magazine under the urging of writer-editor Eric Flint, which achieved great success— to the point the first two unserialized magazines have been released in regular print with a third in production (See: Grantville Gazettes and become best sellers in print form). Within the year, Flint talked publisher Jim Baen into trying another experiment, which involves offering free copies of already published works in print forming the basis of what Baen's calls the Baen Free Library.
Since the experiment was again financially successful resulting in more printed sales, Baens has since radically extended the concept and scope of the experment such that most of it's early titles in a given Book series are offered free, and somewhat aged newer titles are periodically offered free as well for a limited time. All Baen titles are in the process of being back-converted to the e-book formats, or for new works, being pre-released as subscription-only serialized e-books similar to the Baen eMagazine experment— in three installments, roughly one third of each work in production.
For additional information, possibly more up-to-date, see Baen Books#Electronic publishing strategy.
In fact, it may be noted that many of the new e-book publishers are former print publishers, and most established e-publishers offer print versions of many of their titles. The line between the two is fast blurring.
E-books have their own bestseller lists, including those compiled by IDPF and Fictionwise. They even have two yearly awards for excellence in e-books. The longest-standing and most inclusive of these is the EPPIE award, given by EPIC since 2000. The other is the Dream Realm Award, first awarded to speculative fiction e-books in 2002.
