Like so many other foreign - or even Thai - learners. I started reading with Maanii. I was pleased, therefore, to see that a brand new presentation of these books online has appeared. Each book is divided into sections (lessons) and for each of these there is an image of the original, a line by line break down - Thai text, audio file, romanised representation of the line then English translation.

It is very much a work in progress and to date the first 4 (out of 12) books have been completed. The web author ครูเหมียว is developing this even further - according to the todo list, to draw from it lessons on Thai culture etc. I'd recommend it
