So, these have been on my server for a few years but they are still a great resource. I believe they were originally written by the US army for troops stationed in Turkey, then improved by some friends of mine these are a 2 year very comprehensive course for learning Turkish. Totally free of charge you can work through them yourself or with a language helper or teacher. You can download them all for free at http://mark.zealey.org/dli_books/ – I’d especially recommend reading the “How to use DLI Turkish Basic Course” document first.
