Intro material for novices
1. An Introduction to Indian Philosophy- Satishchandra Chatterjee, Dhirendramohan Dutta
dated, but a good intro, despite having simplified much of the material
2. Essentials of Indian Philosophy- M. Hiriyanna (dated, good for intro to Vedic schools, bias to Advaita Vedānta, not good for Buddhism)
3. An Introduction to Indian Philosophy - Roy W. Perrett (not dated, well presented, quite brief intro)
4. Classical Indian Philosophy (Vol 5) - Ganeri, Adamson (good intro)
new and updated, written by distinguished philosophers, better than Perrett
5. Classical Indian Philosophy- J.N. Mohanty (not a conventional intro)
Thematically contrasts Hindu & Indian philosophical positions on epistemology, metaphysics, politics, morals, religion, and art. Brilliant introduction by distinguished Indian scholar.
6. A Sourcebook in Indian Philosophy- S. Radhakrishnan & C.A. Moore
The introductory material explaining the selections are often biased in favor of Advaita Vedānta, and translations are crude. It remains useful for its historical and scholastic breadth.
Detailed Intro (updated with good material)
- History of Indian Philosophy , edited by Purushottama Bilimoria (Routledge)
latest and updated among all books in this answer. A compendium with chapters covering even ethics and other interesting topics which the rest of the books don't cover. Contains chapters covering different topics, written by many established scholars.
Further detailed/advanced introductions (not for novices)
- A History of Indian Philosophy (Vol I-V) – Surendranath Dasgupta
An idiosyncratic, but in-depth, survey of Ind phls. Perhaps the largest textbook on the topic. It has dated material.
- A Critical Survey of Indian Philosophy - Chandradhar Sharma (dated. problematic Buddhist views)
-Indian Philosophy: A Collection of Readings (5 Vols) - Perrett (Ed.)
- Encyclopedia of Indian Philosophies - Karl Potter (lit. encyclopedia)
