Abq Leigh Brackett's ESB script in Portales

Hi all, I've long used the site and the forum for research, but have hit a wall since I'm stuck in California. There's a fair amount of interest in the first draft of Empire Strikes Back, written by Hollywood legend Leigh Brackett. When she died in 1978, Lawrence Kasdan took over. He says, "It was an odd job for her, and there's nothing of that draft left in "Empire." ... George had hired Leigh the way anyone would--because, oh my God, she's Leigh Brackett, and because he wanted a Hawksian, goading humor between Han Solo and Princess Leia."

Her biographer has read it, and says "it can be read at the library of the Eastern New Mexico University in Portales, New Mexico, but may not be copied or borrowed off-site." I wonder if anyone lives or travels in that direction, and would have the chance to check its availability, give it a read or even snap some photos?
