The Invisible Web is easily accessible..that is, if you know where to look. Fortunately there are many sites that are set up to be "gateways" to the many databases and otherwise closed-off content that makes up the Invisible Web.
Deep Web Gateways
- The University of Michigan has put together OAIster, (pronounced "oyster") and encourages you to "find the pearls" on the Invisible Web. They have millions of records from more than 405 institutions as diverse as African Journals Online and the Library Network of Western Switzerland.
- LookSmart's Find Articles.com lets you search print publications for articles; anything from popular magazines to scholarly journals. Be sure to check out their Furl tool to organize your search snippets.
- The Library Spot is a collection of databases, online libraries, references, and other good info. Be sure to check out their "You Asked For It" section, where popular readers' questions are featured.
- The US Government's official web portal is FirstGov.gov, an extremely deep (as in lots of content) site. You could spend hours here. It's interesting to note how much stuff you can get done online here as well, such as renew your driver's license, shop government auctions, and contact elected officials.
- Search the vast holding of the UCLA Library online, including their special collections.
- Check out Infoplease.com and its' searchable databases. Results come from encyclopedias, almanacs, dictionaries, and other online resources.

- The Human Genome Database contains anything you would ever want to know..well, about the human genome, at least.
