Education-Friendly Search Engines
For quick answers to reference-style questions, Milligan suggests Answers.com, and wiki-searchers Powerset and AskWiki Beta. For answers on the go, there's even AskMeNow, which trolls wikis from a mobile phone.
Milligan also spotlights shopping search engines, including MySimon, ShopZilla and DealTime. There are also special engines for law and health students, like MegaLaw.com, and PubGene, which finds biology and genetics materials, respectively.
