Ok, hopefully this is the right place to post about this. I'm writing a project on General Relativity and need access to a specific paper. I'm not very good at finding stuff online or in libraries. The paper is: Gowdy, R. H.: "Vacuum Spacetimes with Two-parameter Spacelike Isometry Groups and Compact Invariant Hypersurfaces: Topologies and Boundary Conditions," Annals of Physics (N.Y.) 83, pp 203-241, 1974. I'm on the authors website: http://www.people.vcu.edu/~rgowdy/gowdy.htm and as you can see, he claims that it's available here: http://xxx.lanl.gov/archive/gr-qc The only problem is, I can't for the life of me find it on that website. Secondly, once I find it, how the hell do I access it, most of them are blocked (even when I'm on my university network). This is the first time I've had to do any proper research for a project which is why I'm so bad at finding this sort of stuff. Help please!
