This is a completely new and authoritative modern re-engraved edition.  (It's different from the old Tecla edition in nine volumes which was facsimiles of the original 19th century editions).  All eleven volumes are now (February 2002) available from Tecla in printed form.  For details of the printed version please go to the Tecla site.  

This is the first time that an authoritative edition of all Sor's duets, made from the first editions,  has been made available in score. 

Some of the pieces  in the new Tecla edition are also available here on Hebe as downloadable files (many of them free). The guitar duets are as follows.
