Brickset - All Things Lego Sets

When you're trying to find information about a specific Lego set, the main Lego site can be useful for all the current sets, but it's hard to find information on the old sets (like the Barney set I posted about earlier). That's where Brickset comes in. Brickset is the definitive guide to Lego sets, including sets from as far back as 1966. If you know the set's numerical id (usually a 4 to 5 digit number that appears on the box or instructions) you can just plug that in to the search bar and go right to the Lego set page to get more information, including when it was released, how many pieces, how much it costs on Lego's official shop site, and number of minifigs. From there, each page provides links to additional information such as the actual parts lists, downloadable instructions, and eBay links to current auctions featuring the sets. There's also a nice social element to the site in that you can create lists of Lego sets you own and another list of the sets you want. This is one of my favorite Lego sites and is usually my first stop for information.
