Found it!

Friday, I had one of those moments you want as a librarian. Or as I emailed a friend later, "I just had a rock-star librarian moment, and no one understands it."
Part of my position includes researching and finding articles for the Geologists in my office. One geologist had trouble finding one article, and emailed as such. "I don't even know if this is available to buy, could you try to find it." Challenge accepted! I try the normal sites, the ones I have already learned are good go-tos. Nothing. I try searching for the journal name, and have a particular organization come up in my search. Seeing as this article was originally published in the 1800s, I figure it may be possible it is not available online, and call them to see if they could get us a copy from the archives. They do not have it.
Not to be deterred, I continue searching, determined to find something. I dive deeper into the Google Analytics. I go to WorldCat, thinking maybe, I can get a copy of inter-library-loan (ILL). And there! And finally! I find it. A library we do have an ILL account has a copy. I click through to request, and behold! It is published via GoogleBooks on HathiTrust. Now, here's the thing on HathiTrust, it is free to allied organizations, primarily academic libraries, of which we are not. I quickly send the link to the Geologist, and letting him know I am trying to determine if I can print it, but in the meantime, here is a digital copy he can start reading.
I cannot print the article as a whole. But after some trial and error, I do determine I can print each page individually. So I do. Saving each one as a separate PDF on the Network, in their own folder titled after the author and article. I triumphantly print them, staple them together, and bring them to the Geologist. "So, HathiTrust is academic only?" is his immediate response.
I, in the meantime, am on the top of the metaphorical world in that moment. :) WorldCat feels like my own special hat-trick.
