Shifting and Reshifting Books:
In order to take away the monotony of appearance of shelf arrangement and to introduced an element of novelty, books have to be reshuffled to keep in tune with the changing popularity of subjects with the reading public. While this cannot be done too frequently, the entire library may be reshuffled once in five years. But this is necessary, though it involves extra work and some dislocation in service.
Assistance to Readers: Readers often need advice and help in locating and identifying books of their interest. Although reference assistant may do this job, the maintenance staff who have a closer knowledge of the contents of me library could go to the name of their colleagues in the reference section.
Maintenance of Book Tags: Book tags carry call number of books fixed at the bottom of books or on their spines. This helps the arrangement of books on the shelf. These book tags get damaged or worn out after repeated use and they have to be refixed if they get soiled. In many libraries, book tags have been replaced by tooling, a process by which call numbers of books could be written on the spines or at the bottom of the covers. This will reduce the work of the library.
