Definition

The Wikipedia (11:44, 7 July 2006 (MEST)) entry provides the following definitions: “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"” ... “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.”

History

Ardito (2000) describes how Andries Van Dam, a professor of technology at Brown University in the USA, coined the phrase "electronic book" while working on the first hypertext system during 1967 and 1968 on an IBM 360 mainframe, and that in 1968, Alan Kay conceptualised an e-book called Dynabook, a portable, interactive personal computer with a flat panel display and wireless communication. Though e-books are not new, their uptake has been slow, especially when compared to other e-formats such as e-journals and e-newspapers. One reason for this is because e-books have been available in many formats and these formats are often incompatible and non-interoperable.

Typology

DSchneider distinguishes the following major forms

  • e-books that only can be read on specialized devices.
  • e-books that have been desigend for reading on standard computers (including mobile devices). Typical formats are HTML or PDF (but with adapted pagination and line length). Such books also include navigation features such clickable crosslinks, indexes, etc.
  • e-books in plain text format. This is how the Gutenberg project started. This format is also frequent for short "how to install something" manuals.
  • digital books that are meant to be printed. Typically these are PDF files with a page size that doesn't fit on our current low-resolution screens (even my 1200x1900 monitors). Sometimes, paper

books are scanned and redistributed as huge PDF files


Standards and Software

Formats

Firstly, one has to distinguis between the formats used to write the book (source) and the delivery formats.

Encoding formats for initial authoring:

  1. Any sort of word processor format, in particular MS RTF/doc.
  2. Any sort of XML/SGML based encoding
  3. TEX/Latex

Formats that are both used for authoring the source and reading

  1. HTML
  2. Several XML languages,
  3. CHI (MS Compressed HTML Help) that allows to distributed a set of HTML files, graphics and metadata as a single zip file
  4. IMS Content Packaging, maybe the most popular format for e-learning texts.

There are several delivery formats, most of them proprietry e.g.

  1. Adobe reader in PDF format (Ebookreader);
  2. PostScript (PS)
  3. Hiebook reader in HI format (home page);
  4. Microsoft reader in LIT format (home page);
  5. Mobipocket in PRC format (home page). Works on most PDA types.
  6. Netwton eBook in PKG format.
  7. Open electronic book package format
  8. Palm reader in PDB format (see home page)
  9. Image formats such as JPG, TIFF, GIF, PNG (typically used for either scanned texts or visually rich formats).

Software

On-demand generated books:

A new trend may be on-demand generated books, e.g. with either PDF libraries or XSLFO to PDF pipelines, one can quite easily implement book output from databases or different file formats.

  • A Mediawiki extension allows to print an article as PDF
  • Efforts spend into Mediawiki book production may soon lead to easy pipelines for producing books from a series of selected articles
  • Standards like DITA are specifically made for such endevours.
