Question

A catalog cannot be a list of anything, arranged in some order.

Answer 1

I believe what this statement is referring to is catalog.

It's a commonly misspelled word.

A catalogue of a company, store or any brand is generally the list of it's available products arranged categorically with the general description, technical specifications and few images of each product clicked from different angles.

Catalogues make it very easy for a customer to go through all the products without physically viewing each and every one of them.
