A basic bibliography on textual reuse can be found at the end of my Introduction to the Reuse of Texts in Indian Philosophy, available Open Access on Academia.edu and on the website of the Journal of Indian Philosophy.

** Jacob has been so kind as to send me his thesis (in Danish language) and an English abstract of it. The relevant part of the latter reads as follows: “I continue with a discussion of tradition and innovation in classical Indian scientific literature based on Sheldon Pollock’s notion of “the Shastric paradigm” (Pollock 1985), and link it to a sample analysis of quotational techniques applied in the Florence Fragments. The main conclusion drawn is that while Pollock and others tend to focus on commentaries as the sine qua non in traditional innovation, my analysis shows that a more subtle, and ultimately more powerful, manipulation of original material is likely to take place in the act of transmission itself.” (emphasis added) If I am interpreting correctly his thesis, the quotational techniques identified by Jacob are: 1. polyphony (the use of many sources on the same topic), 2. fragmentation (the division of a single textual passage in several parts according to the topics dealt with), 3. recontextualisation (of a given textual passage in a new context).
