Personal registrations
Some resources require you to register the first time you use them (e.g. Box of Broadcasts), and some offer additional options if your register. Registration emails often end up in junk or spam folders, so if you don't receive them look there.
Journals
The record for every journal which the university provides access to is listed in Library Search. As well as details about the publication, the record shows our complete holdings in print and online. We only have partial access to some titles, so older back-copies or recent issues may not be available.
Browser issues
This is less of a problem than it once was, but sometimes, problems with accessing e-resources (and e-books particularly) can often be resolved by changing your browser.
