NOTE: The acronyms on the left refer to file extensions. A file called "War and Peace.txt" indicates that you have an electronic copy of the book War and Peace in "TXT" or "Plain text" format. Also, a "Y" in a box means that a device is compatible with the corresponding file format.

*The LRF extension is also sometimes known as BBeB or "Broad Band eBook."

*1-Available through Kindle firmware update 2.3.

**For Sony Reader owners: Sony's Readers indirectly support some files via conversion. Word (i.e. DOC) files are supported indirectly through Sony's eBook Library program, which will convert such files to RTF (your computer must have Microsoft Word installed).

***For Kindle owners: Unprotected versions of the following files can be sent to Amazon via your Kindle e-mail account ("name"@free.kindle.com) for conversion into the Kindle format: Microsoft Word (DOC), PDF, HTML, TXT, RTF, JPEG, GIF, PNG, BMP, PRC and MOBI.

Keep in mind that some "compatible" files won't run if they have DRM or copy protection.
