Sometimes you may have an OpenAthens URL for a main vendor platform, but need to highlight a subsection on your AZ list. We are keeping a document of some tricky vendors where you can scavenge and edit local information for working URLs.

Another good resource for URLs are the sheets FALSC used to Athenize the colleges. Broward probably has the most sample links. Don't forget to edit any URLs you scavenge to have your redirector or, in some cases, your customer ID in the URL.
