This search tool is a quick way to start your research on a topic.
You can search for one topic, such as "photography". This would get you a list of all the library resources with the keyword "photography" mentioned in the entries in this system, which would be a lot!
Or you could do a search for "photography and history" without the quotes but with the word AND. This would get you all the resources that have entries in this system that have BOTH the words "photography" and "history".
Important note: Don't forget that there are about 600 other databases that you can use that might not be represented in Start Your Research.
