CAT is the Starlink Fortran subroutine library for manipulating astronomical catalogues and similar tabular datasets. This manual is intended for programmers who plan to write applications which use the CAT library to manipulate such datasets. It is introductory in the sense that it contains sufficient information to enable a programmer new to the CAT library to write applications which use it. The version of the library intended for use in conjunction with the Starlink ADAM programming environment is described. All the subroutines in the interface to the library are covered. However, the principles underlying the library, and their justification, are described only insofar as they affect its use.
