The USGA maintains a lot of their old articles from the Green Section Record on their web site. The GCSAA has some, too but I think most of the archives are limited to members. Your super might give you his passcode to get in. (He shouldn't by rule, but I have heard of it happening) Golf Industry Magazine has an online archive.
Lastly, you could volunteer to help get the course ready for a tourney or big weekend (think Memorial Day in a month) as a grunt laborer, planting flowers, or whatever and ask if he will let you mow one green, rake a bunker, go along on the spray crew, etc. at the same time. That might actually be a first!
