Hi everyone, was wondering what you all do to keep track of books that you need when you are out and about at a flea market, con, store etc. and you are flipping thru a long boxes of comics? Do you keep a checklist, google, go to ebay.com on your phone?
For example, I made a punch list of key issues of titles that I collect and keep it on my phone. I can pull it out quickly if needed when I am out. Trying to remember what I have and need can be cumbersome. How do you keep track when you have 1000's of books?
