I have a copy of a spiral-bound booklet with yellow covers called "The C Programmer's Reference" by Morris I. Bolsky of the Systems Training Center, AT&T Bell Laboratories, (C) 1985. A curious little snapshot of 1980s pre-ANSI C. I posted a picture of the front cover (with table of contents) at https://twitter.com/fanf/status/1475407500946157570 I think I rescued it from the office clear-out in 2013 when Cambridge University Computing Service moved out of the old city-centre offices. I probably picked it up from a stack of old books that were to be chucked; wherever I found it, I can't remember who it belonged to. And now I no longer work for the University, it has come home with me.
