The .lit filename extension, short for literature, is a proprietary filename extension of the eBook file format LIT developed by Microsoft. The format was initially released in 2000 and at the time was only compatible with Microsoft Reader. Though DRM support was one of the strong selling points of the LIT format, wide spread DRM circumvention discounted its utility in favor for competing open formats. This among other reasons caused Microsoft to officially discontinue support for the format by 2011 and cease further sales of eBooks based on the format completely by 2012.
The LRF format is a proprietary format developed by Sony in collaboration with Canon, as a document and text encoding standard for the Broad Band eBook file format. The format specifically targeted Sony portable eBook readers and was capable of encoding both text, pagination, and images. Being unencrypted, LRF encoded files do not enforce DRM. This is in contrast to the LRX format which is also part of the BBeB eBook file format which does support encryption for DRM files. The Sony eBook store announced in July 2010 a discontinuation of support for the LRF format in favor of the public and open EPUB format.

The LIT format was extended from Microsoft's compiled HTML help format. The format includes support for digital rights management to enforce copyright material. This is however an optional feature. The format had no support for editing or exporting but in later years software programs were developed that allowed LIT files to be converted into formats that supported these features.
The LRF format is an XML derivative. It represents the compiled and compressed binary format of the BBeB file. The structure of an .lrf file included a header, an object stream, and an object index. Though the LRF format is a proprietary asset, many freely available programs are able to convert and or open LRF files for viewing.
