The library has a general guide to deciding on keywords to use when searching databases and indexes. It includes advice on how to narrow or widen your search and what to do if the results from your search aren't what you're looking for.
The library also has a guide on how to find the full text of an article after you've found it in a database. If you still can't find it after looking at the guide, please email me or use the Ask a Librarian options for getting help. If the library doesn't have access to the article, you can request it through InterLibrary Loan and a scanned copy will be sent to you.
