Serials (magazines and journals)
My favorite childhood TV show was the 1960's Batman. Every new episode I would carefully write down the villain, the main characters, and the name of the episode. I would then make specific lists (ie. episodes with Batgirl, episodes with two parts, etc) off of the main list to answer any further questions. This strange nerdy hobby was probably a sign of my future in libraries. And, it is in an odd way similar to the work I do at PCC today.
