My character is trying to research and follow a clue/ lead in something they are investigating. They just have three letters and nothing else to go on - not much of an idea what it is - but this is all they got so they are going to try. Might be an acronym for a business, or an organization - that's all they know.
I'm stumped as to what resources they would be able to use to try to find anything out. They are currently based in a small town in the South West that probably doesn't have a great library. I'm not even sure where one would start looking in a library. Newspapers? Business listings? Stock reports?
They also have resources - or favors they can call in from more populated locations - so presumably someone else in a less crappy town or city is also looking - but where or what at I'm still not sure.
I was a kid in the pre-internet days so I remember card catalogs and microfiche but have no idea how research works when its not just "find a book on kentucky" or "when did a president die?"
I tried googling 'resources in libraries in the 1960's" 'research pre google' - I mainly find history of libraries - and data storage but no idea where someone would go for information or what they would even try to look for.
