I have my Master's degree in Library and Information Science, University of Washington.

Library tourist: Austria (2), Canada (2+), England (Oxford Bodelian), Ireland (5), Italy (15+), Netherlands (2), Scotland (6+), and probably more I can't recall at the moment.

USA: 100+ easily; I have been to 47 states and pretty much went to libraries in every city I have ever been -- partly because of my involvement in ARLIS.
