Set theory by Julia Robinson I used to have a set theory textbook downloaded free from the internet. I lost my laptop in the airport of a city in Eastern Europe, and it was not found (or perhaps “not found”) by the airport security. I now try to rediscover the file. I remember the author was a female mathematician from Berkeley. From an internet search I believe that it might have been Julia Robinson, but I still can’t find the book.
It had a fair number of exercises and I believe it covered Gödel’s incompleteness theorem. 
I would be grateful for help to find the book. 

if you google the title of your questions, one of the links shown is to the collected works of Julia Robinson, and google books does indeed show you a discussion of Godel's incompleteness theorem on one of the pages
