EPUB is a file format standard created by the International Digital Publishing Forum based on a profile of XHTML 1.1 and Zip-based packaging for use by creators and users of electronic books. It is "reflowable" which means that the text can be easily reformatted for different sized e-book readers. The Online Library of Liberty has begun a ePub Pilot Project to explore the possibilites of this open format.

Description from the IDPF webpage: ".epub" is the file extension of an XML format for reflowable digital books and publications. ".epub" is composed of three open standards, the Open Publication Structure (OPS), Open Packaging Format (OPF) and Open Container Format (OCF), produced by the IDPF. "EPUB" allows publishers to produce and send a single digital publication file through distribution and offers consumers interoperability between software/hardware for unencrypted reflowable digital books and other publications. The Open eBook Publication Structure or "OEB", originally produced in 1999, is the precursor to OPS.
