|The main objective for storage of books in the FictionBook format is its accurate keeping of the book structure accompanied with the provision of effortless converting (including automatic) of FictionBook files to other popular formats: txt, doc, rtf, html and so on. Beside that, many reader applications allow to read the FictionBook format without converting.
|The FictionBook format does not specify the appearance of a document; instead, it describes its structure. For example, there are special tags for epigraphs, verses and quotations. All ebook metadata, such as author name, title, and publisher, is also present in the ebook file. This makes the format convenient for automatic processing, indexing, and ebook collection management, and allows automatic conversion into other formats.
