There are two websites which I would recommend before reading and researching more widely on the subject.
The first is TEL Studies. The site was compiled by the late Jeremy Wilson and is a glowing testament to a life's work. The site is now static and hopefully it will remain as the de facto web resource.
The second is the T. E. Lawrence Society. If you are serious about researching or just plain enthusiastic about TEL, then why not join?
