FB2 (FictionBook 2.0) is an open XML-based ebook format created in Russia in 2004. Unlike EPUB it describes the structure of a book (chapters, epigraphs, verses) rather than its appearance, in one plain XML file. It remains hugely popular in Russian-speaking countries, and most cross-platform reading apps support it.
