E-book
Definition
The Wikipedia (11:22, 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
(Anurada & Usha, 2006:48)
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
