I subscribed to all sorts of newsletters, and at least one was dinosaur specific. I would also write professors at local colleges with questions and usually get a response.

Also worked at the library and could order just about any book available. At that point most libraries would order books if they didn’t have them already.

But mostly newsletters and science journals until BBS became more common and user friendly when we first started having available computers.

I worked for a low income apartment complex that started doing AirBnB. It’s already a 2-3 year waiting list to get a rent controlled low income apartment but they were taking units off the market because they could make more money renting them by the night.
