The utility that I see is that as things are digitized the "dead tree" identifier is often included in the metadata that accompanies the digital file. This makes it possible to go from legacy data (read: library catalogs) to the digital data. > Not sure I understand the use case (i.e. the value of retrieving > another identifier). Because the same "dead tree" item is being digitized multiple times in different locations under different projects. It's an interesting situation because where we once had an ISBN that identified EVERY copy of that "manifestation" we will now have many different copies (different because they were digitized separately). Those copies will probably have a variety of identifiers associated with them. > > One thing to keep in mind is that although the numbering schemes are > independent, they can be thought of as hierarchical.

First, ISBNs only came into being in 1968. Nothing before that has one. Many items have NOT been cataloged by LC, many are NOT in OCLC, and oftentimes the records that you are working with have munged, stripped out, or lost the identity of the identifiers that are left. It's great luck if you find one clearly marked identifier in a bib record. kc > > kyle > -- > ---------------------------------------------------------- > Kyle Banerjee > Digital Services Program Manager > Orbis Cascade Alliance > [log in to unmask] / 541.359.9599 > > -- ----------------------------------- Karen Coyle / Digital Library Consultant [log in to unmask] http://www.kcoyle.net ph.: 510-540-7596 skype: kcoylenet fx.: 510-848-3913 mo.: 510-435-8234 ------------------------------------
