This is not strictly speaking Persepolis related, but certainly worth noting. The Internet Archive has posted online the first 16 volumes of the publications of the Mission archéologique en Iran (cited variously as Délégation en Perse; Mission archéologique de Susiane; Mission archéologique de Perse, and commonly known as MDP).
Of particular interest for Persepolis is V. Scheil's MDP IX: Textes Elamites-Anzanites : troisieme serie. If you simply must use a hard copy, you might be able to find one at a library near (or not so near) you, or you might borrow mine, if you're nice to me!
