After reading the Chowdhury section and the Library of Congress booklet I am thoroughly confused. I understand the need for such a system and I generally understand how it works, however I wonder if there might be a more updated way to catalog, a simpler way then MARC. Do we really still need these machine readable tags? Do all of the numbers really need to be there? Its great that libraries can share data on books that they’ve received and cataloged, but isn’t there a more human-readable view?
