Odyssey is free electronic document delivery software from Atlas Systems. It was designed to remove the cost barrier in electronic document delivery software while delivering a product that is easy to use and administer. The Odyssey software utilizes the open Odyssey protocol published by Atlas Systems and integrated into the OCLC ILLiad ILL management system. The standalone module allows sites to send and receive electronic documents to and from other Odyssey sites, OCLC ILLiad sites, and any other vendor’s software that supports the Odyssey protocol.

The Odyssey software is available to all libraries at no charge to add efficiency to interlibrary operations regardless of their level of activity.
