May I make another suggestion........... Be prepared with WHAT you want to research/look for..........this Library is so "AWH" that you will lose your train of thought if you don't stay focused on what you are looking for........ I suggest going to the TSL site, thumbing through the card catalog and get a feel for the Library.........see what they have, make a plan...........just my two cents worth...........it is so hard to stay focused there............pj
