"Card Catalog" Storage Boxes

I found a shelf with boxes at a flea market for $100. It looks like a card catalog but is just a shelf with boxes on it. The boxes are smaller at the top and longer as you move down. The boxes are labeled with numbers and labels like Fantasy, True Crime, Sports, ect. so the shelf was used to store books. I took it home and put it in my garage for storage. 

I went to the flea market to look for a storage shelf but found something much better then just a regular shelf. I really didnt know what I was looking for but when I saw this I had to have it. I have always wanted a card catalog for storage but this was even better because the drawers are so large.

I do not have a truck so I paid the guy I bought it from $40 to deliver it 40 miles to my house. It fit perfectly at the back of the garage next to my toolbox.

At this time I am still organizing the contents of the drawers. I do plan on labeling the drawers but I am still mixing and matching things. I am putting the things I use most often at the sides. Some things I have combined like eye protection with ear plugs and stuff like that. What I like most is how large the drawers get as you go down.  I have lawn mower blades with room for other hardware in one of the bottom drawers. To me this is basically a giant well organized "Junk Drawer" 

Here is a variety of drawers. I am open to any suggestions as far as organizing.
