Hello, I just started a job in a visual resource library. I was left with minimal explanation of the classification schemes and cataloging of certain parts of our collection. I was wondering if anyone can point me to good resources. I am interested in reading up on what is in our library (that is if it is credible) Here are some examples: A slide of an aerial view of Canterbury has the following call number: AMB C16 B1 I know that AMB stands for Architecture-Medieval-Britain. I also figured out that the C16 is cuttered for the name of the building, however I am unsure how B1 was derived. Other slide images have different endings. For instance, the view of the nave toward the choir for canterbury cathedral is AMB C16 L1. Does anyone know about this method? __________________________________________________________________ Mail submissions to [log in to unmask] Administrative matters (file requests, subscription requests, etc) to [log in to unmask] ARLIS-L Archives and subscription maintenance: http://lsv.uky.edu/archives/arlis-l.html Questions may be addressed to list owner (Kerri Scannell) at: [log in to unmask]
