Besides the Shri Sai Satcharita and the Brihat Guru Charitra, what other Guru biographies are mentioned and what is their publication status or fame?

The preface mentions a few other Guru biographies. As detailed in Chapter 0, there is a scholarly work by Shri Samarth Sadguru Tembhe Swami, also known as Vasudevanand Saraswati Maharaj. However, it had not become as famous as the one written by Shri Saraswati Gangadhar. Another biography was reportedly written by Shri Samarth Sadguru Dattatreya Maharaj of Balekundri, but it did not seem to have been printed or published at the time of writing. Additionally, a separate, much older work from Wadi called Laghu Guru Charitra is also noted as being distinct from the main Brihad Guru Charitra.
