The Library-cum-Documentation Centre of the ICHR has over the years developed into a fairly large and well-informed reference library. It has a collection of approximately 67,000 books/journals and regularly subscribes to approximately 110 foreign and Indian journals/periodicals.

The Library also provides reprographic services. During the period under report, approximately 8,700 exposures were made available to scholars and researchers at a nominal rate of 50 paisa per page.

The Library purchased about 778 books published in recent times largely on Indian history and allied disciplines, including reference books and books relating to the history of Asia and neighbouring countries.

The Library has been extending reading, reference and consultation services to scholars. About 1,585 visits were made by scholars during the period under report to the Library from various universities/institutions pursuing studies on various aspects of historical research.

The Library-cum-Documentation Centre is fully computerized and is a member of the DELNET (Delhi Library Networking). And by virtue of having secured membership of JSTOR, the Library has access to unaffordable journals as well as rare and old numbers of historical journals.

The reading room of the ICHR Library is kept open from 9.30 am to 5.30 pm on all days, with the exception of Sundays and gazetted holidays. Scholars are welcome to offer suggestions for the improvement of the Library.
