I found this site via the Internet Resources Newsletter: Issue 129
“Subject Finder is developed by Teum Teklehaimanot to help students, teachers and lecturers find educational websites easily without being overwhelmed with a huge number of search results. It is designed to search only educational websites which contain tutorials, learning and teaching materials such as Accounting, Arts and Design, Biology, Business, Chemistry, Computing, Construction, Counselling, Economics, Electronics, Engineering, Geography, Health, History, Law, Languages, Mathematics, Physics, Psychology, Reference, Science, Social Science, Sociology, Travel, etc.”
You can browse by subject or carry out a keyword search. Although the site says that it searches only educational web sites, that does not mean it is restricted to academic pages. I found some good quality resources on a number of topics from organisations such as trade and professional associations. I am definitely adding this service to my collection of “specialty” search tools.
