The proceedings differ from those published previously in two important ways. Firstly, the papers were published prior to the meeting for distribution to all delegates who attended the meeting in Baltimore. Secondly, none of the discussions at the meeting are included, which has the advantage of smaller size (only 2 volumes, less than 1,600 pages) which should make the books more attractive to libraries and other repositories of research literature. A CD-ROM, comprising all the material covered in the 2 volumes, is also included.
