10: Bucknell University, http://www.facstaff.bucknell.edu/rbeard/diction.html

Incredible site devoted to multilingual dictionaries of the Bucknell University. They say in their about us section:

Reference books and webs have enjoyed a long and happy history together. This website indexes on-line dictionaries, thesauruses, and such like containing words and phrases. Preference in selection has been given to the free online dictionary of high quality. However, any downloadable or subscription dictionary may be listed if exceptionally rare and/or unusually well-executed. A few inceptive word lists and glossaries of languages otherwise not represented have also been included, as encouragement to continued development.  Word-mavens, scholars, translators, and others who fuss with words might wish to encourage the various dictionary-makers responsible for this trove by using their products and sending suggestions and support by email. Comments, additions and corrections pertaining to any dictionary should be directed to the manager of the specific dictionary site. Suggestions, additions, and corrections for this site and its contents should be directed to the owner, Robert Beard. A simple click on his name should get his attention.
