There are
several books dedicated to flying tailwheel airplanes, but personally I see little point in swotting up. Tailwheel flying (takeoffs and landings, really; the rest of the flying is the same as for tricycle airplanes) is not the mysterious black science that some people believe. My advice is not to worry about doing a lot of theoretical study, as personal instruction and hands-on appplication are really far more important.
If you absolutely must read something, review chapters 8 and 16 in Langewieche's
Stick and Rudder. Barry Schiff's
The Proficient Pilot and Richard Taylor's
Fair-Weather Flying also have short chapters on tailwheel technique. On the Internet, see
here and
here.
Have fun! What sort of airplane will you be learning on?
