Organizing Your Lego Collection, Part I: Sorting Bricks

Welcome to Part I of OYLC (Organizing Your Lego Collection)!
This section discusses sorting out and organizing loose bricks. Links to other sections are found at the end of this entry.

Introduction
I was first introduced to Lego at about three years old. At that time, I lacked an understanding of the importance of organization, so every set I acquired ended up in an enormous, jumbled mess. Unfortunately, this is the fate of many peoples' collections. When I was a bit older, I realized that I would run out of room if I didn't do something about it. Thus, I began experimenting with many different organizational methods. By now, I have spent about ten years undoing this disaster, and I have finally found a method that works remarkably well. I have discovered effective methods and tricks for nearly every step of the process. By sharing my own skills and experience, I aim to help others organize their collections in considerably less time than it took to figure it out myself.
Know that your collection must be organized to suit your needs, so you have to find out what works for you. If my methods don't quite work out for you, feel free to do something different. I will do my best to offer ideas for other ways to do it. However, I know that my methods do work, and I have spent a decade honing and perfecting my strategies to operate as smoothly as possible.
The way you organize your collection revolves around what type of builder you are. My process assumes that the goal is to have all sets sorted out, completed, and organized effectively. If you only buy sets for parts and enjoy building from one enormous pool of bricks, you may want to stop after sorting your pieces out. Feel free to skip or ignore steps that are not applicable to your needs. Organization is a process, and it will take time. My intention is merely to help you along the way and make sure it takes you less than a decade to do it.

The First Step
In order to sort a collection, it has to be in one place. Gather all sets, instructions, and loose pieces into one area. This may result in a frighteningly large pile, but don't be intimidated. Make sure you have absolutely everything you can find, since this will prevent frustration later.

Sort Out Bricks
Many people are unsure how to sort their pieces. I have found that it works the best by far to sort by color first, then type, then size. You don't have to sort it all three ways. In fact, I only used color up until the last year. If you only sort by color to start, keep each color in a separate container. I recommend wide, shallow boxes that are easy to sift through. The cardboard boxes from cases of soup cans work extremely well, and shoe boxes can work, too. If you have smaller quantities of particular colors, use smaller containers such as whipped cream tubs. As you sort out sets, your unsorted bricks will take up less space. It is important to move to smaller containers, to fit your bricks. This not only provides a sense of accomplishment, but also prevents the wasting of space. If you sort by multiple sub-categories, I recommend cases of divided, sliding trays, similar to what I use now.

My unsorted bricks, which once took up an entire room,
now fit comfortably in two chests of divided trays.

The box to the right is what my black bricks once filled to the
brim. Now they fit in a  little sorting tray, several times smaller.

During sorting, a decision must be made. Between 2003 and 2004, Lego changed the tints of Light Gray, Dark Gray, and Brown very slightly. The "New Grays" are more bluish, causing the name of Light/Dark Bluish Gray or "Bley", for short. The newer shade of brown is warmer, with the name "Reddish Brown". If you own unsorted sets from both sides of the switch, then you must choose whether to go to the trouble of distinguishing them. If it doesn't bother you, then don't worry about it. If it annoys you to no end like it does me, then you should sort out each shade individually. The differences between the browns and dark grays are easily noticeable, but the light grays are an immense pain. When trying to tell if a piece is Light Gray or Light Bluish Gray, I recommend working under natural or fluorescent light, rather than incandescent. Also, placing the undetermined piece between known pieces of either type can help you to compare them.

 Other Tips
Take it a little at a time-- it's usually impossible to sort it all at once anyway, so break it into manageable chunks.

Don't get bored-- sorting is monotonous. Turn on some music, a TV show, anything to keep you going.

Enlist help-- it's a massive undertaking for one person. Consider asking friends or relatives to help get it done faster.
