----------------------------Original message---------------------------- The hardest thing to estimate in any insurance appraisal for library collections, of course, is the labor and processing time to put these collections together. That includes cataloging time, as well as acquisitions, and any physical processing that is necessary. I suspect that these "hidden" costs could add another 40%-50% to value of the collection. Does anyone have some hard figures on what these costs could add up to? Tony Hess, Art & Music Librarian Colby College Waterville, ME 04901
