In my own (rather limited) rankings of university libraries around the nation, Harvard University's Cabot Science Library is no better than the fourth-best science library in the nation. Ahead of it are:
- The University of Michigan's Shapiro Science Library (excellent holiday hours, everything sorted by Library of Congress codes);
- The Massachsetts Institute of Technology's Science Library (has everything one needs, but hours aren't the best and the basement is downright scary);
- The Ohio State University's Science and Engineering Library (limited selection, but open round the clock).
