Hi, Unlike Link/360, Serials Solution's Summon API is extremely cumbersome to use - requiring, for instance, that requests be digitally signed. (*) Has anybody developed a proxy server for Summon that makes its API public (e.g. receives requests, signs them, forwards them to Summon, and relays the result back to a HTTP client?) Serials Solutions publishes some PHP5 and Ruby sample code in two API libraries (**), but these don't appear to be fully fledged nor easy-to-install solutions. (Easy to install here is defined as an average systems librarian can download them, provide the API key, and have a running solution in less time than it takes to install Wordpress.) Thanks! - Godmar (*) http://api.summon.serialssolutions.com/help/api/authentication (**) http://api.summon.serialssolutions.com/help/api/code
