Please be careful not to attach item records for published copies of books to bibliographic records for uncorrected proofs, advance reading copies, uncorrected galleys, etc. Whatever the publishers choose to call these, they are prepublication releases for reviewers and, because they have not received final editing, constitute different editions from their published counterparts.
Records for advance reading copies have edition statements that distinguish them from published editions of the same work, and we try to make sure that we add the genre heading "Proofs (Printing)" to each bib record.
If in doubt, please call the LINC cataloging center. We'll be happy to help.
