Q. Which databases require special care when providing links to use later?
Links to EBSCO should always start: https://ezproxy.losrios.edu/login?url=https://search.ebscohost.com. When you are browsing EBSCO databases, the url that shows in the browser's address bar looks nothing like this. If you provide that URL to others it will not work; it may work at the moment but will break later.
Films on Demand
Always use the "Share" feature of Films on Demand to find the permalink. This permalink should include a wID parameter. If you don't see wID= in the URL, that's a bad thing; the user will not be able to get to the resource.
JSTOR, Gale, others
Using the URL from the browser is usually ok, but also check to see if a permalink is available.
It is preferable to have the ezproxy piece at the beginning rather than in the middle of the domain. A URL converter tool is available that can accomplish this easily.
