Is there a minifigure museum? I have a gallon jar (& more) of minifigures that my kids have mixed and matched. Is there a website I can reference in order to put the minifigures back in their original configurations (including their gear)?
The website Brickset.com has an extensive database of sets, digital copies of instructions and a Minifig database built in cooperation with Bricklink. The layout and style may be a little more user friendly than the Bricklink catalogue and if you register on the site you can keep track of your collection.
The Unofficial LEGO Minifigure Catalog lists every minifigure ever produced, up to 2010.
At BrickLink you can browse through, what seams to be, all the existing Minifigures.
This link is the query that seams to returns most of them but you will have to dig around in the other Lego themes(categories) to find the other ones.
