Search the websites under "Web Resources" when you have a BROAD topic or an INTERDISCIPLINARY topic (that is one which uses information from a variety of disciplines--rather than just civil enginering, computer engineering, etc.).
*** Remember that the library's databases are just clicks away (via the "Databases" tab on this guide), and that they provide more specific information and for selected databases--the full-text of an article that is already paid for vs. the same article you maybe asked to pay for if you find it on the web.
