It has come to my attention that there is a website that houses a dictionary of collections; it is called The Collectionary. It houses hundreds of different Collectionaries that you can join.
They have expert collectors called moderators that help add items to each collection under that category. The site offers history, facts or unique attributes regarding a particular collectible or item. It allows you to find the places you can find the item; whether it is new or something you remember from when you were younger.
Purses Collectionary carries many high end purses. Maybe sometime in the near future MacramePurses will be one of their collections.
Let me know if you found anything you were looking for at the collectionary.
