How do we call a person who colects things?

Sometimes it depends, like a stamp collector is called a philatelist, and an arctophile is a person that collects teddy bears. If the particular collector doesnt have a particular title they are just called a collector of.. Then you have what is known as The Junk Man, or woman, depending. This person collects everything under the sun, usually hoping to eventually sell the things he has, so this person will usually have a storefront. Then there are hoarders who simply cannot throw anything away whether it has value or not. This person wouldnt part with their things if their life depended on it. I hope it will help you.
