During our work with HTML and its relatives XHTML and XML blechtrottel brodaktschns also came across e-books. Unfortunately there is no international standard in this field and the number of e-book readers and formats is growing.
At the moment Mobipocket (.prc, .mobi) and EPUB (.epub) formats seem to be the most rewarding to look into. The first, which originated on PalmOS, is still widely spread, whereas the second is open source. Also, both formats are rather easy to convert into each other, if need be.
We started with Mobipocket Reader, available for Windows and older mobile operating systems, such as PalmOS, Windows Mobile and Symbian. It does import EPUB files.
The more up-tp-date choice is FBReader, which supports Windows, Linux/Android and MacOS and reads, among others, both formats. Another reader and the first choice for converting e-book formats is calibre. Amazon's Kindle (app) supports Mobipocket files.
The software we use to create e-books, namely Mobipocket Creator is available free of charge, so there is no limit to your creativity! Well, there is actually, it doesn't produce EPUB files. There is a free editor for both formats called Sigil, we haven't worked with it, yet.
The number of free e-books available on the net is impressive, so, blechtrottel brodaktschns decided to contribute.
At the moment there are two e-books available. Others will follow, as time permits. They are available in Mobipocket and PDF. Dutzend nach Taxen is also available in open EPUB formats.
