Could you detail the previous authors and texts that have chronicled the life and stories of Shri Sai before the creation of this new book?

According to Chapter 2, several authors and works have documented the life of Shri Sai. Das Ganu, following the tradition of Mahipati, wrote two books: 'Bhakta-Lilamrut' and 'Santa-Kathamrut'. The former specifically describes the sweet life of Shri Sai in three chapters, while the latter contains a knowledge-story told by Sai in its 57th chapter. Other sources mentioned include Raghunath-Savitri’s 'Bhajanmala', miscellaneous poems by Das Ganu, works for Gujarati people by Amidas and Bhavani Metha, and a series of stories published in Pune by devotees under the name 'Sai Prabha'.
