Of course I use a famous search engine a lot, as well as the Wikipedia. Over the years I found some other sites of interest.
Turkish news in English
Although the English sometimes was a bit weird I read with much pleasure the Turkish Daily News, in Turkey on paper, at home on a site. This is the modern version.
sözlük - Dictionary with a voice
The best spot I know to quickly translate a Turkish word into one of several languages. Over the years the functions have improved.
Turkish language information
I have been in touch repeatedly with the author of this site, who manages to teach you some of the intricacies of the Turkish language. I wish I had a bit more time to study it more often.
Travel information by USA based Turk
One of many informative sites I know that give you information about the country. Lovingly made.
Information on drugs from my job's organization
Though it has nothing to do with either Turkey or Syria this information is provided by experts and may be useful. There is a Turkish version also.
site about the Hittites
Very informative site about this early people.
