I already documented this in a different thread, so I figured I'd add it to a more logical place.
I thought about my solution for a week or two and settled on this design. I went from 42 of those Sterilite containers to everything fitting on this wall. I like this solution much better because I can easily thumb through the library. No more opening 6 containers before I find what I'm looking for. Good riddance! I think what you see in the photo is $100 IIRC.
Brackets (@ my local store, the price drops to $1.60 each if you buy 10 or more):

wood (gotta pick through to find the straight ones)(pick smoother wood if you don't want any chance of splinters):

string:

and various screws to hold it all together.
1. screw the brackets to the wall, make sure you hit studs
2. screw the 1x2s to the brackets, pre-drill the screw holes so you don't split the wood
3. tie one end of the string to the bottom shelf's back wood.
4. criss-cross your way up to the top shelf and then back down to the bottom. I think each string was about 18' IIRC. Be sure to keep the string as tight as possible as you weave it in and out of each shelf. I wound around each wood piece one time as I passed by it; I'm hoping this helps retain the tension.
5. tie the other end of the string to the bottom shelf's front wood.
6. repeat 3-5 for as many "bookends" as you want.
finished product:
I like the result. it is plenty stout for the discs it holds. The string is for "bookends" so the discs have something to rest against. Otherwise, the discs could turn sideways and fall through between the two wood pieces. I did one bracket on every stud, I didn't skip any studs. I also did a string on every stud/bracket, then one in between every stud. Probably overkill, but I don't care.
There are several ways to achieve the bookends, the string was the cheapest and easiest. The string will likely stretch and loosen over time. I can always tighten or re-string if needed. Plus, the string is adjustable... so if I want to section off types of discs, I can just move the string or add more. There are more robust solutions, this one works fine for me. I just need to add some kind of bookend to the top shelf so those can stand upright too.
My biggest beef is that the brackets break up the shelf space because the discs want to sit lower than the bracket will allow. Use taller boards (maybe turn the 1x2s onto their short edge?) to have un-interrupted spans of discs.
