List of Helpful Websites for Beginning Collectors I recently wandered into my father's basement where my brother and I used to have our "game room" setup. I stumbled across a massive amount of LEGO that we had collected over the years.  Since then, I've had the urge to get back into LEGO, taking a more adult approach at collecting them.  

I was wondering if there were additional sites besides the one's I've found that may shed some light for a beginning collector.  Also, feel free to include any tips that you think may be beneficial in this quest! Here are the list of sites I've come across:


http://www.lugnet.com/
http://lego.wikia.com/wiki/LEGO_Wiki
http://www.brickset.com/
On top of the already mentioned: 


http://www.lugnet.com/
http://lego.wikia.com/wiki/LEGO_Wiki
http://www.brickset.com/
http://www.peeron.com - Large set database and instruction scan library
http://www.bricklink.com - Lego marketplace selling millions of used and new parts and sets. This is also a nice reference for information and
inventories related to old sets.


I personnally use the following ones as well:


http://www.brickfactory.info/ - Online collection of Lego Sets instructions
http://rebrickable.com/ - Site allowing you to see what other Lego set you can build from your existing collection


After that, it all comes down to forums and more specialized websites that directly depend on your area of interest (sci-fi, military, castle...), your language, and your location.
