I'll probably get some more of these boxes as they're waterproof and reasonably-sized for paper. I still have a lot of maps acquired from other sources, so I'm sure I'll fill them. While polypropylene isn't as good as mylar d for archival storage, it's easier to find big storage tubs made of polypropylene. At $3.40 a box directly from the store (cheaper than the price at the link above), they're pretty cheap.
I rather feel like I started collecting paper maps from the auto clubs at the end of an era. The California State Automobile Association closed its 12-person cartographic unit back in 2008, citing a drop in demand for paper maps. GPS/satnav units have their place, but it'll be a long time before we'll have one with the display size and detail of a paper map.
I haven't seen anyone post a reasonably comprehensive list of maps keyed to AAA/ACSC/CSAA map ID number so I think I may put that up in Google Docs or something when I finally have them all entered in.
