The act of examining the arrangement of books and other materials in the stacks of a library to make sure that all items are in correct call number sequence. Usually performed by a library staff member known as a page. Synonymous with shelf checking.
The process of verifying that materials are in their correct position on the libraries shelves. Library staff "reads" the call number that is present on the spine of each item in an area to make sure they are in the correct ascending order. Any materials that do not belong in that area are removed and sent to the circulation department for reshelving, a log of which areas have been completed is usually kept to prevent more than one staff member reading the same section at the same time. This process is continuous so that materials can be found by staff and patrons.
