I don’t believe I’d ever heard of package libraries before I came across this a couple weeks ago. In the case of Indiana University, it appears that the Bureau of Public Discussion (whose mission precedes the table of contents in this bulletin), distributed such packages. According to this document, the University of Wisconsin pioneered the Package Library movement.
I want to know more. I’ve found one other document in the library so far. If anyone has any knowledge of these libraries, please share!
