Library databases are online collections that search quality journals and other academic sources. There are a large number of databases available because there is so much information; there is no one database that covers all the resources available. Some databases will be directly focused on your subject, while others cover a wider range of subjects so are useful for multi-disciplinary topics and topics that don’t fit a specific subject.
Which databases you use depends on what you’re looking for, it’s a good idea to start with Search + Find because it indexes a large number of our collections. To access one of our databases directly by name, use the A–Z listing.
