An addendum, in general, is an addition to a certain document, subsequent to its edition, publication or diffusion.

Specific uses

In books

In a book, an addendum (sometimes referred to as an "appendix") is a supplemental addition to a given main work. It may correct errors, explain inconsistencies or otherwise detail or update the information found in the main work, especially if any such problems were detected too late to correct the main work. For example, the main work could have had already been printed and the cost of destroying the batch and reprinting is deemed too high. As such, addendums may come in many forms — a separate letter included with the work, text files on a digital medium, or any similar carrier.

In contracts

In other documents, most importantly in contracts, an addendum is an additional document not included in the main part of the contract which may contain additional terms, specifications, provisions, standard forms or other information. A contract addendum may also be called an appendix or a rider. Addendums are often used in standard form contracts to make changes or add specific detail. For example, an addendum might be added to a contract to change a date or add details as to delivery of goods or pricing. The Addendum should be referenced in the contract, or the contract should be referenced in the addendum, so that it's clear to which contract the addendum is modifying.

Schedules and exhibits are sub-categories of addendums, with schedules being related to numerical and time information, such as pricing and time-schedules, and exhibits used for examples of standard forms and different types of evidence or models.

Plural

In the plural, both the Latin addenda and the English adaptation addendums are acceptable.
