Catalog and catalogue mean exactly the same thing. The only real difference is spelling. Catalog is the preferred spelling in American English, while catalogue is the standard spelling in British English. Both words refer to a list of items, products, books, services, or information arranged in an organized way.
For example:
- American English: I ordered a new catalog from the furniture store.
- British English: I ordered a new catalogue from the furniture store.
Neither spelling is more correct than the other. The best choice depends on which variety of English you are using.
