I had a boyfriend in college who had boxes upon boxes of his “favorite” comic books. (Which ones were his favorites? All of them!) I found it a little weird, but hey, collectors are kind of different, right? Well, now I have a son who wants to collect comic books. I realize that for some, the physical book is the only way to go, but if you want to be a little more eco- and space-friendly, do it with a download.
The Comic Zeal iPhone app has a gorgeous interface (love how you can see your collections on physical shelves, on the overview), and the flexibility it affords even the most avid reader to skip around, zoom in, and organize makes it a fabulous way to take your whole collection with you anywhere.
