The word that is used to describe a person who collects dolls is plangonologist. This word is an obscure noun that is used when a collector is specifically obtaining various specimens of dolls. The dolls are mostly small models of human figures. They will often be a baby or girl and will be used as a child's toy.

In the comprehensive book by Catherine Christopher, "The Complete Book of Doll Making and Collecting" (1971), the earliest documented dolls go back to the ancient civilizations of Egypt, Greece and Rome. The use of dolls as toys was documented in Greece around 100 AD. They have been made as crude, rudimentary playthings as well as elaborate works of art.

There are a number of reasons plangonologists collect dolls. It may be done for nostalgia, entertainment, Christmas purposes, therapeutic value, home decorating, hoarding, and celebrity worship.
