Clicking on the Advanced Search link on Google's Home page opens a search form that allows limiting your search topic to specific domain (.edu, .org, dot.gov, etc.) and/or to documents of a specific file format (Word, PDF, PowerPoint, Rich Text, Excel). Often, documents in non-HTML formats are publically available, but do not have any "official" link on a website, such as when someone puts a PowerPoint presentation up for interested people who may want follow-up on a talk. Google regularly searches for these, but the results can get lost in a crowd of HTML documents. Other features include how to find pages that link to a page and finding pages that are similar.

A joint venture by Intelliseek, Invisible Web Catalog provides links to more than 7,000 specialty search resources. A handy feature is its Hot List.

Focuses on scholarly resource collections, electronic journals and books, online library card catalogs, and directories of researchers. Unlike many Invisible Web search tools, Infomine allows simultaneous searching of multiple databases.
- Librarian's Index to the Internet
