The Peninsula Library System (PLS) is a cooperative library system of 35 physical library locations throughout San Mateo County, California. There is one central sorting and delivery location in San Mateo, and four trucks which deliver books and materials between the libraries. Sorting is done primarily through an Automatic Materials Handler (AMH) sorting mechanism but is also done manually.

This class is the first in the Sorter series. The Sorter I works under close supervision and performs routine sorting functions. It is distinguished from the Sorter Il by the amount of sorting and supervisory experience required.
