Do people really think "edited by J. Garland, Cambridge Carbonates UK, J.E. Neilson, University of Aberdeen, UK, S.E. Laubach, University of Texas at Austin, USA and K.J. Whidden, USGS, USA"
is more helpful and unambiguous to users than, "edited by J. Garland, J.E. Neilson, S.E. Laubach, and K.J. Whidden"? To me at least the former looks like a mix of individuals and corporate bodies. And that is what 2.4.1.4 without the optional omission (which, unfortunately, LC and PCC don't seem to like) leads to. --Ben Benjamin Abrahamse Cataloging Coordinator Acquisitions, Metadata and Enterprise Systems MIT Libraries 617-253-7137
