“Cataloged is the American English spelling, while catalogued is the British English spelling; both mean the same thing and are correct depending on the region.”
Using “catalogued” or “cataloged” the wrong way can make your writing look careless—but choosing the correct one is easier than you think. Both words are correct past tense forms of the verb meaning to organize, list, classify, or record items in a system.

The Origin of Catalogued and Cataloged
The word comes from Greek. The Greeks used katalogos to mean a list or register. They made lists of ships, soldiers, and library books. Then the Latin language took the word as catalogus. Later, French changed it to catalogue. English borrowed the French version in the 15th century.
For 400 years, everyone spelled it catalogue. The –ue ending was standard in all English books. Then Noah Webster changed everything. In the 1800s, Webster wrote American dictionaries. He believed English spelling was too complicated. He wanted to make it simpler. So he dropped the –ue from many words. Catalogue became catalog. Dialogue became dialog. Monologue became monolog.
This is why we have two spellings today. Catalogued or cataloged meaning is exactly the same. Only the spelling changed. One group of English speakers kept the old way. One group chose the new way.
