My father was a retired librarian (and folk singer and ethno-musicologist) who wouldn't be comfortable at home in his retirement without many of the accouterments of a typical library office, so I inherited his paper cutter, some of his filing cabinets and materials, and because he was the first audio-visual resource librarian at his college, many of his machines and tape editing materials. And where his collection falls short, it seems interesting stuff is turning up these days at thrift stores. I picked up a robust three-hold punch that I use often, and other things are part of my office setup in the sunroom where my eBay processing takes place. Postal scales, for example. Good rulers. I'll stop here before I catalog it all.
