The College library is the key resource of information for the academic community. The Library at St. Teresa's started functioning in 1925 with the birth of the college. Initially named the Mother Veronica Library in honour of the memory of the Superior General of the CSST congregation, it underwent many remarkable changes through the years. The Library was housed in the Main Block in 1975 when the college celebrated its Golden Jubilee. The Golden Jubilee project was completed in 1981, when the library achieved the form similar to that which it enjoys today.
The Central Library underwent a major refurbishment and transformation in 2010-11, with the work being completed in 2011. In addition to the resources that have been added in terms of books and journals, the Library refurbishment project has resulted in a completely automated, state-of-the art, digitally controlled library system which is fully equipped to deal with the demands of the student and teaching body.
The library that encompasses three floors can now be accessed through a single door entry system through RFID (Radio Frequency Identification) cards that automatically scans and records individual IDs and allow entry. This new system allows for centralization and easy management and supervision of resources.
The main Reception Counter situated at the entry level acts as Information, Issue and Property Counter. A comprehensive library management solution, in the form of the latest software technologies, has been incorporated. This new system allows for the annual stocktaking of books, items owned, orders made, acquisitions, cataloging circulation and public interface for users.
The library boasts N-List, 78,084 books, 21 International Journals and 76 National Journals. In addition to N-list, the library also contains E- Repository, D-Space Digital Repository Library services. Students are given training on accessing and using N-List [Digital Library].
