Libmobi

C library for handling Mobipocket/Kindle (MOBI) ebook format documents. Current version supports reading and parsing functions.

There is a simple program included in the project: mobitool.c. It may serve as an example how to use the library.

What works:

reading and parsing:
- some older text Palmdoc formats (pdb),
- Mobipocket files (prc, mobi),
- newer MOBI files including KF8 format (azw, azw3),
- Replica Print files (azw4)
recreating source files using indices
reconstructing references (links and embedded) in html files
reconstructing source structure that can be fed back to kindlegen
reconstructing dictionary markup (orth, infl tags)
handling encrypted documents

Todo:

writing MOBI documents
process RESC records
exporting to EPUB documents
