Here are a few sites on the open web that might be helpful.
Google Books is valuable because you can search inside the pages of books. It can be a good way to find a book that discusses an issue relevant to your needs. You can read the "snippets" that Google provides, or get the full book by using the book title to search the TLU library catalog. If the book isn't at TLU, you can request it through Interlibrary Loan.
Although Google Scholar lacks the precision and organization of library databases, it has several useful features. When you search from a campus computer or update the library links in Google Scholar Settings, it can link to the library's full-text content. It can also show you a "cited by" list, which helps you to see how influential a particular article was. Click on the "Cited by" link to see a list of citing articles.
Visit WorldCat to see books from libraries around the world. You can't read them online, but you can see which ones are at TLU and which ones are at libraries nearby. If TLU isn't at the top of the list of libraries, that means the book isn't located here and you will need to submit an Interlibrary Loan request.
