This can hold a lot of cards. The plan: fill out and insert cards every day until it’s full, or embarrassingly, still hungry. Who gets into the Rolodex? Anyone I’ve met in person who I’ve exchanged names with at minimum, or can somehow say of them, “I know/knew/love/hated/can’t forget/played drums for or just plain met –him/her/that bastard/that angel/that genius, etc.” Amount of detail may vary. May contain nuts.
Found an old IBM Selectric Manual which showed how to make a “pleat” to hold smaller cards so they are amenable to typewriting. This removed the last obstacle to starting this Rolodex project–since common sense has long since waved me on with a resigned sigh.

I used a Rolodex for years, planning on switching back to one. So much easier than having to turn on the computer every time I need to look someone up.
