Note that while some databases or ebooks have unlimited simultaneous users access, others may have limited simultaneous users or a single-user license.
One example of a single-user database is the Neighborhood Change Database 1970-2010
(https://guides.lib.vt.edu/neighborhood-change).
You may get the following message when more than one user is trying to access the database:
