Why Convert ORG to FB2?

Converting Org-mode documents to FB2 format makes your content accessible to millions of readers in Russia and Eastern Europe, where FB2 is the dominant e-book format. If you've written fiction, translated literature, or created content for Russian-speaking audiences, FB2 is essential.

FB2 excels at fiction and literature. The format includes semantic elements specifically designed for novels: epigraphs, citations, poem stanzas, and annotations. When you convert your Org-mode manuscript to FB2, your book gets proper structural markup that readers expect.

The format is widely supported by popular e-readers and apps in the region. FBReader, CoolReader, and PocketBook devices natively read FB2. Many digital libraries and book sharing communities use FB2 as their primary format due to its excellent metadata capabilities.

FB2's rich metadata support is particularly valuable for library organization. You can include detailed information about the book, author, series, sequence number, genre, and more. This metadata helps readers organize large digital libraries effectively.

Frequently Asked Questions (FAQ)

Q: What is FB2 and why is it popular?

A: FB2 (FictionBook 2.0) is an XML-based e-book format developed in Russia in 2004. It's the dominant format in Eastern Europe due to its excellent support for fiction, rich metadata, and small file sizes. Popular readers like FBReader and CoolReader were built around this format.

Q: Can Western e-readers open FB2 files?

A: Most Western e-readers don't natively support FB2. However, you can use Calibre to convert FB2 to EPUB or MOBI. Apps like FBReader are available on all platforms and can read FB2 directly on iOS, Android, and desktop computers.

Q: Will my Org-mode structure be preserved?

A: Yes, the hierarchical structure translates well to FB2. Org headings become FB2 sections, and the nesting is preserved. FB2's semantic structure is particularly suited for novels with parts, chapters, and scenes.

Q: What about footnotes and annotations?

A: Org-mode footnotes are converted to FB2 notes, which appear in a separate notes body. Readers like FBReader display these as popup annotations when tapped, providing an excellent reading experience for annotated texts.

Q: Are images included in the FB2?

A: Yes, images are embedded in the FB2 file as Base64-encoded binary data. This makes FB2 self-contained with no external dependencies. Cover images are also supported and displayed by most readers.

Q: What's the difference between .fb2 and .fb2.zip?

A: FB2.zip is simply an FB2 file compressed with ZIP. Since FB2 is XML (text), compression is very effective, often reducing file size by 70-80%. Most FB2 readers handle both formats equally well.

Q: Can I convert FB2 to other formats later?

A: Absolutely. Calibre can convert FB2 to EPUB, MOBI, PDF, and many other formats. The semantic structure of FB2 is preserved well during conversion, making it a good intermediate format for distribution.

Q: Is FB2 good for technical documentation?

A: FB2 was designed primarily for fiction and may not be ideal for technical documentation. It lacks features like code block syntax highlighting and complex table support. For technical content, consider EPUB3 or HTML instead.
