I started making a list of my comics today so I would have a handy field reference guide for when I am at the comic shop and not entirely sure if I have an issue or not. It’s not done yet as I still have to go upstairs and start tackling the pile o’ comics next to my bed (I like to read before I go to sleep) and I haven’t even started with the box sets with figures yet ^^;  I’ve been collecting comics off and on for a little bit over a year, I like to try and keep a narrow focus on DC in particular Joker and Harley Quinn otherwise I see this hobby spiraling out of control. I think I have a fairly good cross-section of Batman/Joker comics I have read a lot more than I own due to a friend of mine having an absolutely massive collection that I can leech off of and read it beforehand to see if I will actually like it or not.  I do read stuff other than Batman, but for the most part I know what I need/have of the other stuff so it isn’t as pressing to me at the moment as I am not actively hunting anything.
