First off the vendor has to be able to do authentication based off of ip only. This usually isn't a big issue, and I've only ran into one small vendor out of the hundreds that libraries subscribe to that couldn't handle it in some way.

Second we need a generic link to the resource. By generic I mean that it doesn't have any information in the url that is specific to any one library. We keep a database of generic links here at the office, which lets us add database links to your locally purchased databases tab pretty quick, since the same link will work for any library.

Lastly you just need to give the vendor your OPLIN proxy IP address. All the authentication in the world won't save us if the proxy ip address doesn't have access. OPLIN proxy ips always start with 66.213.41 and have a 4th octet of whatever their FSCS is. For example, Ada (OH0001) is 66.213.41.1. We will try to setup authentication for anything that you ask for, so as usual if you need anything, give us a call.
