Search Engines
Ask.com, searches the Internet via easy queries.

Google Advanced Search features lots of options for narrowing your results. For example, searching for Stacey Dennick in the first box, "all these words" brought up 641 results, most of them related to some other Stacey and random Dennicks. Using the second line, "This exact wording or phrase" resulted in 57 pages, all them about me. The fourth line, "don't show pages that have..." is useful for eliminating commerical sites that clutter up your results. Add ".edu" to the last line, "search within a site or domain" to bring up only scholarly domains.

Direct Search has links to many “invisible” resources that aren’t entirely searchable/accessible from tools like Google.  Scholarly.
