A parts book, parts catalogue or illustrated part catalogue is a book published by a manufacturer which contains the illustrations, part numbers and other relevant data for their products or parts thereof.

This article includes a list of references, related reading, or external links, but its sources remain unclear because it lacks inline citations. (November 2009)

Parts books were often issued as microfiche, though this has fallen out of favour. Now, many manufacturers offer this information digitally in an electronic parts catalogue. This can be locally installed software, or a centrally hosted web application. Usually, an electronic parts catalogue enables the user to virtually disassemble the product into its components to identify the required part(s).

In the automotive industry, electronic parts catalogues are also able to access specific vehicle information, usually through an online look-up of the vehicle identification number. This will identify specific models, allowing the user to correctly identify the required part and its relevant part number.
