Besides Annasaheb Dabholkar's 'Shri Sai Satcharita', who else has written biographies about Sai Baba?

According to the preface, Shri Dasganu Maharaj, a poet who was worthy of Shri Sai Baba's grace, also wrote two biographies of Baba. The first is found in his 'Bhaktalilamrut' (Chapters 31, 32, 33), and the second is in 'Bhaktisaramrut' (Chapters 52, 53). Chapter 0 describes these works as undoubtedly excellent and heart-touching, though they are noted to be much shorter than the 'Shri Sai Satcharita'. The stories contained within them are largely the same as those in Dabholkar's more extensive work.
