'cataloger' originates from the Greek word 'katalogos', where 'kata-' meant 'down' and 'logos' meant 'word' or 'reason'.

'katalogos' transformed into the Latin word 'catalogus', and eventually became the modern English word 'catalog' through Middle English.

Initially, it meant 'a list or register', but over time it evolved into its current meaning of 'a person who creates or maintains a catalog'.
