## Definition

making a systematic list of things, like books in a library or items in a collection. It helps people find exactly what they are looking for later.

For teachers: the present participle of 'catalog'; refers to the systematic classification and recording of items in a collection. Often involves assigning metadata or identification numbers to ensure retrieval.

## Examples

- She is cataloging the new books for the school library.
- The museum staff spent the entire summer cataloging thousands of ancient coins found during the recent excavation.
- By meticulously cataloging every specimen found in the rainforest, the researchers created a database that proved vital for future conservation efforts.

## Synonyms

indexing, listing, classify, organizing, categorizing, recording, inventorying

## Pitfalls

- Not "He is cataloging about the files." but "He is cataloging the files." — Cataloging is a transitive verb and does not require a preposition like 'about' before the object.

## Usage notes

- The verb is transitive and takes a direct object. This spelling is the American English variant; British English typically uses 'cataloguing'.
