MinerQuest is the easiest way to search as many of the UTEP Library's databases + its catalog at once. Results will include articles of all types, books, e-books, government documents, streaming videos, and encyclopedia articles. A good all-purpose search tool.
Search the whole internet for books and e-books, some of which are free to read online. If the book isn't free, search for it at the UTEP Library, where it definitely will be free.
