Why cant I search more databases in the articles and databases tab?
There are two reasons for the limitations on the number of databases searchable for each subject in this tab. The first is that not every database is cross-searchable and so not all could be included. The other is that we limit the number of databases for each subject to five to speed up the delivery of results. Adding more databases to a subject set would result in a longer wait time for results and possible time outs.
