----------------------------Original message---------------------------- We are planning for a new geology library and would like to hear comments about using hanging files, like those made by Spacesaver, for U.S.G.S. series. We currently file these envelopes in 13 file cabinets and hope that we could save limited floor space by using hanging files. Are there storage or retrieval problems we should consider? Comments from librarians familiar with these type of compact storage would be very helpful at this stage of our planning. Thanks! Karen Berquist Geology Library College of William & Mary
