If you're like me, you have what seems like a bazillion comic books. You're constantly rebagging and reboarding, and filing. The last thing you want to have to do after all that work is worry whether or not you have a certain issue of something when you go to the comic book store or a con. I mean, sure, you could go through every single comic you have and see if there are any books missing, but wouldn't you rather just have something on your phone telling you what you need?
The software that The Editor and I use is called Comic Base. It's a wonderful system. You just catalog your collection as you go, and you're able to generate tons of reports! The reports include things like: what comics you're missing in a particular run, whether or not you have any multiple comics, the current value of your comics, variant covers, etc. The program will even give you little pictures next to each comic that you have (or need) so there is no second guessing when you're at a con! These reports can be printed out, or saved on your smart phone for easy access. This way, you don't have to be carrying a notebook full of chicken scratch around with you!
At $40 I personally think that this is the best investment you can have for your comic collection. Class dismissed!
