The boxed version included a paper manual.  I dont know if SmithMicro has kept that option. All versions (box and download) include the manual as a pdf file in the program folder, along with a python methods manual. 

There are lots of tutorials online from renderosity , daz3d and many other site.  I dont remember what tutorials are included in the manual.

You can download and try Daz studio for FREE and see if it holds your interest before spending the money on Poser .
