Yoga books and references

Lately I have been trying to read more about yoga and have found several books which are now on my reading shelf:-
1. Light on Yoga Sutras Patanjali by BKS Iyengar 
2. Sanskrit Glossary of Yogic Terms (for reference only)
3. Yogic Management of Common Diseases by Swani Karmananda
4. Autobiography of a Yogi by Paramahansa Yogananda
5. The Mind and its Mysteries by Sai Baba
In addition to the above, these are the other books which I have been recommended to read later on:-
6. Teaching Yoga by Mark Stephens
7. The Bhagavad Gita
I am also looking for books on modern yoga. Would love to hear from you if have any recommendation 🙂
