The author should provide justification for carrying out this research when Frank Friendly, Gary Galoshes, and Wendy Weinstein have all reported work which overlaps strongly with the results reported here. Now, Joe is a mythical character - in more ways than one. Science is somewhat like an unfinished brick wall. We look at the work already done and we lay a brick in an appropriate place. In some cases even more than one brick.
Some people are sufficiently lucky to lay one or more bricks in the bottom row.
But even these must know about the other walls. Part of the fun of the library is found in the hunt - which in my opinion is almost as important as the laboratory research itself. Technology has helped us in this hunt. In spite of the budget restraints which have been forced upon our Library, the excellence of our Library remains. We are justifiably proud of both our facilities and our dedicated, friendly, and helpful library staff.
