eBook Formats
ePUB
This format has created an industry-wide standard for eBooks, and its popularity has surpassed other formats. It’s based on various technologies like Open eBook and XHTML 1.1 but is unique in its own way. The ePUB format creates solid formatting for eBooks of any shape and size. The standard of ePUB is maintained by the International Digital Publishing Forum (IDPF), and it has the most popular DRM option called Adobe Content Server. Devices like Windows and Mac computers with Adobe Digital Editions are extremely compatible with the ePUB format.
Amazon Kindle

Microsoft LIT
DRM-protected LIT files are only readable in the proprietary Microsoft Reader program because the .LIT format, similar to Microsoft’s CHM format, also includes Digital Rights Management features. This case makes it easy for other third-party readers, such as Lexcycle Stanza, to read unprotected LIT files.
