Like some of the others above, I'm constantly looking at my collection. I'm either pulling out some raw books to read or gazing at my slabbed books, rearranging them, re-boarding and re-bagging some, checking out values of some of the books while I look at them, re-boxing some, picking some to finally sell as I either want something else more and these can now go...and on an on. It's simply just very fun to do something with my collection. I only have three comic books so I can do all of the above pretty quickly.
