The Sperse Search Engine provides you with both a thumbnail image of each site and test info after you submit your query. In addition, you can view the website without leaving the search results page. And it has a pretty clean interface.
All of those reasons make it particularly accessible to ELL’s. I don’t think I’ll add it to The Best Search Engines For ESL/EFL Learners — 2008, but will include it on my website under Search Engines.
Thanks to Make Use of for the tip.
