Dear Sree Sudheer,

Thanks for your communication.

Since we are writing Call Numbers in pencil. Naturally they are being written in manually. The alternative way is to copy/paste the numbers from other sources which is not desirable. I am narrating why it is so.

There is a book called WHERE THERE IS NO DOCTOR by Dr. David Werner. In my Library of an ICMR institute, the book was classified under Medical Science (610+). When I joined an ICSSR institute and purchased the same book for the Dept. of Sociology, the same book was classified under "Sociology"  (310+)

So had I copy /pasted the Call No.from my previous organization, this book would have been isolated in my new Organization. Later after nearly a decade we developed a Sizeable collection on Health Economics & Medical Sociology and started running courses on that topic as we got a fairly large fund from an International Organization, for benefit of the scholars we shifted a portion of the old collection and there we put new Call No. under Medical Science for those books to be exclusively used by the people studying/ working on it.That is why we need to put call No. afresh and manually through pencil. Never-the-less, the World Bank has several publications on Agricultural Economics, Climate Change, Public Health. HIV/AIDS etc. which bear varied Call Nos in different Institutions according to their focus of Research. I had been one of the full Depository Librarians of the World Bank for more than a Decade. So you can take it as a official comment.

Sincerely,

Siddhartha S. Ray, Calcutta
