Bringing Web Search To New Depths

I am always looking for interesting ways to access deep web information – documents that are not necessarily html but are still accessible via the Web. Another player in this game is RefSeek, a search engine providing advanced search capability and an index of over a billion documents including web pages, books, encyclopedias, journals, and newspapers. There is more than simply document search, though: RefSeek now offers definitions, math calculations, and a reference directory. Definitions show above regular search results with relevant links. Math calculations are natural language for math equations and conversion. And perhaps the coolest feature is the reference directory, which offers a curated list of hundreds of references sites, so you have NO EXCUSE to fall back on Wikipedia.
