I suggest that priority be given to books that can be converted to dictionaries as their impact is greater. Here is a list of a few books. I have shared some of these books here. I will share the others upon request.
Primary Texts
- सुभाषितावलिः (Subhashita work)
- शार्ङ्गधरपद्धतिः (Subhashita work. If सुभाषितावलिः+शार्ङ्गधरपद्धतिः are done, all the big five Subhashita works will be made available)
- अन्योक्तिमुक्तावलिः of हंसराजगणिः (very comprehensive anyokti collection)
कुवलयानन्द- काव्यादर्श + रत्नश्री commentary (oldest AFAIK and best)
