pocket part

Primary tabs

A pocket part is supplemental material found inside the back cover of certain legal reference books. When examining such books, these small booklets are consulted to ensure that the most current law is examined.

For example, in Rudovsky v. West Publishing Corporation, the U.S. District Court for the Eastern District of Pennsylvania noted that pocket parts referred to annual updates to a law treatise in the context of this case.
