re: #91 Targetpractice
They were that thing that was being phased out when I first started going to libraries. Then again, I admit most of the time I found books by just wandering the shelves and seeing what looked interesting.
I think I referenced them once or twice. Maybe. Probably just so my mom could show me how they worked.
By the time I was looking up books for things like research reports, it was all computer.
