Answer

You can try to get History of Jainism by K. C. Jain through these options:

• Jain libraries or Jain temple libraries — many Jain centers keep books on Jain history.
• University libraries — especially libraries with Indian religion, Indology, or Jain studies collections.
• Used book sellers — older Jain history books are often available second-hand.
• Jain book publishers or Jain granth bhandars — ask if they have a copy or reprint.
• Inter-library loan — if your local library does not have it, they may be able to request it from another library.

Explanation

K. C. Jain’s works on Jain history may not always be easily available in regular bookstores, so Jain religious bookshops, academic libraries, and second-hand sources are usually the best places to check.

If you are near a Jain temple or Jain center, you can ask their library or bookstall directly. They may also guide you to a Jain granth bhandar that sells such books.

Takeaway

Start with a Jain temple library or Jain granth bhandar, then check academic libraries and used book sources if it is not available there.
