Weeding 

In course of time some  books in the library become outdated (e.g. books with statistics). Some time later research result into making information in earlier edition inaccurate. Similar are books less circulated or fatigued one. Not all old books are valuable in each library. The need for  weeding out such books can not be over emphasised. The following steps are suggested for weeding out unwanted material. 

• Arrange such books in correct order 
• Assemble the necessary relevant catalogue record 
• Put a disposition slip in books to be withdrawn. 

A tabular record for books withdrawn/weeded as per illustration may be maintained. In all such cases  approval of the relevant  parent body also must be taken before effective withdrawal/weeding.
