Central Science Library
University of Delhi
The emergence of Central Science Library (CSL) dates back to 1981 prior to that, it was a part of Central Reference Library (CRL), Delhi. However, the need to have a separate Science Library was shown much earlier by Carl M. White in 1966 who recommended "that a Science Library be created to serve the departments, which consist of Faculty of Science and that the collection now maintained by these departments and related material in the main library be used to form the nucleus of the new library. A Science Librarian of outstanding ability be employed to take charge of it and that a new building be erected to house the library".
With the growth of the University, the membership of Central Library was also increasing continuously, as a result in due course of time with increasing membership and their changing information needs, it became inconvenient for Central Library to serve the users, belonging to the faculty of science effectively. So CSL was separated from CRL and housed in a separate building to serve members of science faculty .The three-storied building having a carpet area of 22,595 sq. feet with a sitting capacity of 185 seats started functioning independently with effect from 8th April 1981. The administration of CSL is under the Dean of the faculty of science.
The Central Science Library is situated in the vicinity of Science Departments viz Anthropology, Botany, Zoology, Physics, Chemistry, Geology, Environmental Biology and others. The three storeyed library building in red stone and concrete is located in beautiful surroundings of parks, flowers and ornamental trees amidst various science faculties. It is just opposite to and very near to Delhi University Computer Centre. Hence it would always facilitate in its modernization.
It has a total carpet area of 22,595 sq feet and it offers a congenial environment for study and research. The total capacity of the library is about 185 seats with reading halls on 1st and 2nd floors. The library has been organized as follows:-
The ground floor of the library has the Incharge Room, Issue/Return Counter, Membership, Internet Access Facility, Public Catalogue, Acquisitions Section, Processing Section, textbooks collection and the Reference desk.
The first floor of the library has the Periodicals Section. It has three stack areas and display of new journals and a reading room where current issues are arranged alphabetically. Presently the Library is subscribing to 350 journals. The photocopy facility is also available on this floor. The 1st stack hall contains journals in Biological and Chemical and Earth Sciences. The 2nd stack hall contains journals in Physical, Chemical, Mathematical and Natural Sciences.
The 3rd stack hall contains books and journals published before 1970, A/Cs & establishment & binding section.
Departments Served By CSL

SERVICES PROVIDED BY CSL
Library is essentially a service organization to cater to information needs of its users. CSL acquires the documents, processes and organizes them on the shelves for purposeful utilization of its resources and provides various useful services to its users. The various services provide by the library are given below

Library is using a Brown Charging System for charging and discharging of books. The general books and journals can be accessed through open access while textbooks are in close access and are issued for 3 days only. On an average 250 books issued and about 600 books are given for consultation against I-Card per day.
When a particular book required by any user is already issued out, then issue and return counter staff writes down the name of the user and details of that book in a register maintained by them (very shortly such reservation will be undertaken online). When a reserved book is returned back, then if that book belongs to “only for consultation” category then it is retained by 1 day for the user who has reserved it. If the book belongs to “Text Book Section” it is retained till the next day and if the book belongs to “General Category” then it is retained for 3 days.

INTER LIBRARY LOAN (ILL)
No library is self-sufficient today on account of ever increasing such information needs of research scholars and ongoing multi disciplinary research being conducted in the university. So when the required documents are not available in the collection of respective library, ILL facility is used to acquire documents from some other library, for the purpose of use and consultation by its scholars and teachers. Library on receiving written request from its members, arrange for its ILL by sending requisition to the particular library. Similarly CSL also lends documents to other libraries on ILL.
Such services provided to Faculty Teachers and Research Scholars selectively on demand both manually and online from e-journals.

CSL has a provision for reference services. The users who approach the library with a reference query are provided with the required information or source of information. For document tracing facility, which is a part of reference, library maintains a register where users fill the information about the document to be traced such as a Call Number, name of the author and title etc. Usually library takes a few hours to trace the document. CSL staff has lot of information skill both online and manually to provide suitable reference service to users.
