The Classification Scheme

The library uses its own classification scheme for books within the subject field of Physics. Each book is given a code consisting of a 2 digit number denoting subject, a single letter which is usually the surname initial of the first author, and final sequence number. For example, "The Principles of Quantum Mechanics" by P.A.M.Dirac is classified as 60 D 1. The present classification numbers are given in the table:
