Databases work similarly to other search engines, but they are much pickier! So, you have to play by their rules and speak their language to get the best results. That's where Boolean operators come in:
GLDYS is Grafton Library's catalog, which is a great place to start when searching for sources. Just be aware that this search will initially show you materials from libraries around the world, not just those here at Grafton. However, you can choose to refine your search results to only the materials held by Grafton by using the limiters available on the left side of the screen beside your search results.
Google Scholar is a great free resource for finding scholarly resources. Just keep in mind: you are not guaranteed to have full-text access to all of the resources in the results.
