When viewing an article record in EBSCOhost, look for the permalink icon in the far right 'Tools' column. This permalink contains all of the information you'll need in order to log in, so don't add the proxy prefix. You will get a permalink that looks something like this: https://search.ebscohost.com/login.aspx?direct=true&db=a9h&AN=152731890&authtype=shib&site=ehost-live&scope=site&custid=s8881910
When viewing an article record in JSTOR, the persistent link is listed as the stable URL. For articles from JSTOR you'll need to add the proxy prefix https://go.openathens.net/redirector/mchenry.edu?url= to the beginning of the stable url. It will look something like this: https://go.openathens.net/redirector/mchenry.edu?url=https://www.jstor.org/stable/43881653
Within Credo, you'll find a persistent link in the top toolbar. In Credo the link will include the proxy prefix for you, so there is no need to add it. When you click the page link icon you'll get something that looks like this: https://go.openathens.net/redirector/mchenry.edu?url=https%3A%2F%2Fsearch.credoreference.com%2Fcontent%2Fentry%2Fcolumency%2Ffrog%2F0%3FinstitutionId%3D3139
You can use it to link to results, articles, and any other type of page within Credo.
You can use the "Get Link" option found in all Gale Databases (excluding Gale Directory Library) to link back to any page within a Gale resource. You can link to articles, results, and publications using the bookmark function (it'll always be in the same place).
Here is a screenshot from Gale in Context: Science. This link has everything you need to access the database, so you don't need to add a proxy prefix. The link should look like this: https://link.gale.com/apps/doc/A671451029/SCIC?u=crys82357&sid=bookmark-SCIC&xid=52d9a733
If you are creating persistent links from a database not listed here, or if you'd like additional assistance, please contact an MCC Reference Librarian.
