When I was in law school, I wasted a lot of time wondering how big a library would have to be to hold all the reporters and codes in the next twenty years. I do not think about that much any more because I rarely go to a library. But someone still thinks about it. Did you know that the 1958 edition of the U.S. Code had 10 volumes and the 2000 edition had 34 volumes. (No, I was not in law school in 1958). The 1960 CFR had 54 volumes while the 2005 CFR had 230 volumes. For more details, see here.
