I got in a conversation with Harmony today about the process of pitching my songwriting demos back in the early 90's. That relates only marginally to the library in that the market guides I would use were sometimes available for borrowing from the library. More often I would buy the most current one at a book store and then I was free to mark it up willy-nilly.
And then of course there was the mass reproduction of cassette tapes - plus the accompanying business correspondence - and then mass mailings of them in padded envelopes with a whole bunch of stamps you had slobbered on.
With, of course, self-addressed stamped envelopes enclosed.
The times they are a-changing.
But yeah, the library.
