lower than Lo again

Adventures at the library today: after a couple of months of asking around I found out where UIUC keeps old technical reports, like to the NSA and stuff. In a corner of the basement of the engineering library, I dug up one of two precious (to me, anyway) copies of "On the theory of randomly spaced antenna arrays." It's beat up. It looks almost archaeological. It was written on a typewriter! So I take its yellowed, scribbled-on self upstairs to the desk and they say, "Um, I'd better look up how to check this out to you. Where did you get this, anyway?" I felt kind of like Indiana Jones. I'll post a picture.

np: Rooks - "Down"
