A separate Book Bank was established in 1972 with a grant from the U.G.C. The stated objective of the Book Bank, according to the U.G.C., is to make available books on loan to deserving students for the period of their studies. Accordingly, students are allowed to borrow books for long term use (at least two years) from the Book Bank.  This is in addition to the usual quota of books a student is entitled to borrow for home study from the general library and the seminar library. The books in this category consist primarily of textbooks and other related titles. Additions to the Book Bank library are regularly made with the help of grants from the U.G.C. and have been facilitated by Government Grant. The total collection of books in the category is 3471.

The Indian branch of the Church Missionary Society, London, was established within the college campus and its activities were conducted from the college center. The library has, therefore, a rare collection of books and manuscripts relating to Church Missionary Society. So useful is this collection that a visit to the library has become a must for scholars doing research on CMS matters. The utility of this section has been acknowledged by scholars from home and abroad “The Anglican Church in India 1600–1970” Delhi, 1972 written by Ms. M.E Gibbs of St. John’s College Agra; Sri Binoy Bhusan Ray’s “Zenana mission: Role of Christian Missionaries for the Education of Women in 19th Century Bengal” Delhi, 1998 ; “Christian Missionaries on the Indigo-Question in Bengal (1855-1861)” Kolkata, 1989  by Sri Abhijit Datta are few examples of the publications whose authors have acknowledged the valuable assistance that they have received from the college library.    
      The role of the Christian Missions and Missionaries in the usually termed ‘Bengal Renaissance’ has been universally acknowledged. In fact, no history of the process of modernization can be written in India in general, and Bengal in

         St. Paul’s C. M. College is a treasure storehouse of the original source materials consisting mainly of manuscripts and rare printed texts of which the oldest dates back to 1801.The total number of the collection amounts to 1500. The 13 volumes of manuscripts containing the minutes and correspondences of the Calcutta Corresponding Committee of the Church Missionary Society (C.M.S.) range from 1814 – 1913, which forms very important archives. Apart from these documents the college library has a collection of old missionary periodicals, theological books and rare editions of the Bible.         The department of History took the initiative towards a scientific preservation of those historical records and applied for financial assistance to the National Archives of India under the ‘Scheme of Financial Assistance for Preservation of Manuscripts / Rare Books’ for the year 2004 – 2005. The State Archives had given a survey report after a detailed inspection of the library as per the Higher Education State Archives’ Order No.760 – S. A. dt. 8.10.2004. The State Archives had strongly recommended our application.
