It has become apparent that, since the advent of the SciVerse platform, Scopus and ScienceDirect work best with Firefox and Internet Explorer with MS Windows. If you have reports from users that they can’t access these databases, or that they are being asked for login details, check what browser they are using. Users on a Mac with Safari may be presented with a login box or be unable to access full ScienceDirect functionality. Changing to Firefox will usually solve their problems.
I have added a note to the records on the Databases pages.
