Best KP Astrology Books

We at our KP System Forum, see this query very often - "What are the best KP System Books" available in market. Due to regularity of this question being raised, I thought to write it here. In my opinion following books are best suited to learn KP System (Krishnamurthi Paddhati) -

1. Six Reades by Sri K.S. Krishnamurthi, the inventor of KP System (more details can be found at 6 readers of KP Astrology
2. Nakshatra Chintamani (3 parts) By Chandrakant Bhat
3. Books by Jyotindra Hasbe (Available in Marathi, the time I read them)
4. Astrology & Athrishta, magazine edited by Sri KSK, (old copied would be available)
5. Astrosecrets & Krishnamurti Padhdhati (3 parts) by M.P. Shanmugham & K. Subramaniam

Other than Sri KSK's KP System, there are some more systems developed on top of KP System e.g. four steps theory and cuspal interchange theory. I discourage any starter of KP System to go through these theories before understanding K P System properly. It can confuse the learner.

I am sure you will be looking for the place in your town where you can purchase the books. I have created a KP Bookshps section in our KP Astrology Community where you can find the KP booksellers around the world.
