Sometimes you'll see an error message about maximum users/licences/seats when accessing an article or a database. This means that the database has a limit on the number of RMIT users, who can use it simultaneously. If that limit is exceeded, you will not be able to access the resource. To find out if there are access restrictions on a database, look for a note underneath the resource link that will tell you how many users can access the database at the same time.
If you come across this issue, just try again later. If after several attempts you still can't get through, please contact Ask the Library.
