Dear Susan, Definitely consult Table N6! But to make life easier, I devised a cheatsheet with letters of the alphabet clustered under possible Cutter numbers: AB CD EF GH IJK L M N O PQ R S T UV WX YZ .A62 63 64 65 66 67 68 69 72 73 74 75 76 77 78 79 If I were shelflisting a book on Leonardo's Adoration in the LC database, I would consider A62 or similarly low number (always adjusting for titles already cataloged): ND623.L5 $b A645 2007 Battle of Anghiari ND623.L5 $b A647 2009 Belle Ferronnière In this list, the Cutter no. A62 would correctly file the book on 'Adoration' before 'Battle'. The display .xA6-.xA79 is a little cryptic. The Classification and Shelflisting Manual (CSM) G 330, Artists, explains how to use Table N6. The first Cutter number, '.x', represents the artist. The second represents the work of art. If there are a lot of books on one work of art, you may have to distinguish them by work letters: ND623.L5 $b A7 2004 ND623.L5 $b A7 2005 ND623.L5 $b A7 2006 ND623.L5 $b A7 2006b ND623.L5 $b A7 2006c Hope this helps! --Julia ~ Opinions expressed are my own, not necessarily that of my employer. ~ Julia Wisniewski Cataloging Librarian Library of Congress 101 Independence Ave SE Washington DC 20540-4291 ~~~~~~~~~~~~~~~~~~~~~~ Mail submissions to [log in to unmask] For information about joining ARLIS/NA see: http://www.arlisna.org/join.html Send administrative matters (file requests, subscription requests, etc) to [log in to unmask] ARLIS-L Archives and subscription maintenance: http://lsv.arlisna.org Questions may be addressed to list owner (Judy Dyki) at: [log in to unmask] ~~~~~~~~~~~~~~~~~~~~~~
