AuthenticSearch
AuthenticSearch limits your search to minimally commercial, add-free sites with attributable authorship and/or community enforced peer-review. AuthenticSearch is a good source for authoritative information on established topics and is less good for online shopping. Currently limited to domains where English is the official language of the host country.
To suggest a new domain for this search send an e-mail describing yourself (to confirm your identity) along with a carefully reasoned proposal.
