Information Sources and Services




                    Notes              Librarians have been providing this kind of service on manual basis for a long time.
                                       During recent years the trend is towards computer based SDI. It is a highly personalized
                                       information service directed to individuals so as to cater to their requirements.
                                       Bibliography is a list of citations or references to books or periodical articles on a particular
                                       topic. Bibliographies can appear at the end of a book, journal, or encyclopaedia article, or
                                       in a separate publication.
                                       According to UNESCO/Library of Congress Survey, bibliographic control means “the
                                       mastery over written and published records which is provided by and for the purpose of
                                       bibliography”. Effective bibliographic control should be made at subject and national
                                       level.
                                       Reference service, as a distinct function of the library, began in the late nineteenth century,
                                       largely in response to the growing prevalence of publicly funded libraries (both public
                                       and academic) seeking to serve relatively inexperienced and unskilled readers and scholars.
                                       Document Delivery Services are an important component of the Library’s inter library
                                       loan activity by which users’ are facilitated not only to obtain information about the
                                       location of a document but the document itself as well.
