Abstract:

Obsolescence study is useful for librarians and managers of information centers in identifying the use of periodical literature. The present study aims to examine in the light of obsolescence of literature, Annual Aging Factor (AAF), Mean Life (ML) and Utility Factor (UF) of periodicals in the field of chemistry. This is based on references appended to the articles published in Indian Journal of Chemical Technology during the year 1994, 1997 and 1999. Obsolescence of literature was studied and half-life of literature was found to be 11.8 years. Study also applied Brooke's formula for identifying Annual Aging Factor (AAF) and the average value of `a' was found to be 0.9754 and Mean Life (ML) and Utility Factor (UF)were calculated and found to be 16.1958 and 40.65 respectively.
