Can you identify the most significant Guru biographies from Maharashtra mentioned in the preface?

Within Maharashtra, two Guru biographies are highlighted as being particularly famous, comprehensive, and suitable for devotional practices like Parayans. The first, as mentioned in chapter 0, is the "Brihat or Thorale Guru Charitra," a sweet and graceful work by Shri Saraswati Gangadhar about Shri Samarth Sadguru Narsimha Saraswati Maharaj. The second is the more recent "Shri Sai Satcharita," an inspirational biography of Shri Sai Baba Maharaj written by the devotee Shri Govind Raghunath, also known as Annasaheb Dabholkar. The text notes that apart from these two, no other work written in such detail is commonly found.
