Planning for document selection should also cover the personnel or human factor. The people involved in the selection process are the librarian, the acquisition staff, the subject experts and the library authority or selection committee. The ultimate responsibility for book selection rests with the librarian. The acquisition staff are there to help him. But, neither the librarian nor his staff are experts in all the different subjects. Therefore, it becomes necessary to take help from subject specialists. The selection committee may or may not be composed of subject experts. Nevertheless, committee level decisions have the advantage of being more democratic and participatory. You must remember that document selection is not a one man job. It should be the outcome of good team work. Therefore, you must be very prudent in choosing the members of this team. This applies to both the acquisition staff and the subject experts. You need to maintain a panel of subject experts who will be willing to participate in the selection process by giving objective opinions and advice.
