If it bothers you there, this method may not be for you. So you don't lose anything by doing this. I'm interested in. Rather than pulling a box out of the closet, rooting through it until I find the series I want, and pulling each issue I'm looking at out of its individual bag, I can walk over to my bookshelf, scan the spines of my books, and quickly find what I'm looking for. This is especially handy if I want to look through several comics at one time, or if I want to read an entire storyline.
Books are also easier to lend to friends.
When I get it back, I don't have to resort a stack to be sure it's all there. Despite the fact that each comic has seven holes through the spine, I feel a book is less likely to be damaged than a number of individual pamphlets. Bent covers, pages ripped out of the staples, and so forth happen less often or not at all. I really don't want to keep. If I don't want to take up shelf space with them, I know I don't actually like them enough to hang onto.
