Besides the 'Shri Sai Satcharita', what other significant Guru biographies are mentioned in the preface?

The preface in Chapter 0 references several important Guru biographies in addition to the 'Shri Sai Satcharita'. It first mentions the 'Brihat or Thorale Guru Charitra' by Shri Saraswati Gangadhar, a widely studied work used for Parayans. Chapter 0 also discusses a detailed and scholarly biography by Shri Samarth Sadguru Tembhe Swami, though it is noted as not being as famous. Furthermore, two short but graceful biographies of Sai Baba by Shri Dasganu Maharaj are highlighted, found within his 'Bhaktalilamrut' and 'Bhaktisaramrut'. Finally, a much older text called the 'Laghu Guru Charitra' from Wadi is also identified.
