This site presents information describing UIEE (Universal Information Exchange Environment). UIEE is a file format and protocol for exchanging data between dissimilar information systems. The current UIEE v2.44 specification is available, as well as information regarding UIEE products and services.

The current specification was last updated July, 2003. Many new capabilities have been added, in particular the ability to embed object data (such as image files) and four entirely new token sets supporting Antique, Auction, Retail, and Custom datasets. These are presented in a series of tables for reference by developers.

UIEE has been adopted as the de-facto standard for information exchange in the out-of-print (OP) book trade since it was first introduced in 1989. It is the objective of this site to present a comprehensive set of standards which will move the development of UIEE forward to meet the needs of the market in which it is in common use today, and thus increase the likelihood of productive use by all who rely upon it to serve their personal and professional needs.
