Many of our Gale products are under our own account (lom_umichflint) through purchase, subscription, or MeL. Other resources are subscribed or owned under Ann Arbor's account (umuser), and are not not available through Flint's platform. Therefore, some Gale URLs contain the element lom_umichflint, while others have umuser.
Sometimes, replacing the lom_umichflint in the URL with umuser will make the resources accessible. Please let Paul Streby know about any titles with such issues.
