Archival Collection in Open Access

Indian Institute of Astrophysics traces its origin back to 1786, and the Institute has naturally inherited the library and records of the Madras and Kodaikanal Observatories. This collection of archival records has grown over the years to include more than 5000 items in various formats such as manuscripts, photographs, maps, films, awards, hand-drawn sketches, pictures and instruments.

As our open access repository is created to accommodate all the institute’s publications, we have decided to include the archival contents which are out of copyright in the repository for better access. Most of these contents are catalogued, classified, digitized and uploaded in the Open Access Repository with appropriate metadata.

For those contents which are protected by copyright only metadata is provided. Researchers can request the Indian Institute of Astrophysics Archives for full-text of these contents.
