NPL Labels- reference labels

Printed NPL numbers:

NPL numbers reference the general NPL catalog. This is not a physical catalog, but a database detailing what information is associated with which catalog number. These labels are often printed on slips of heavy paper, and placed in the tray with a specimen. 

Historic, incomplete labels:

Much of the historic material has detailed information on the label, but sometimes you will come across a BEG, P, WSA or UT label with nothing but a catalog number on it. These numbers refer to an entry in the physical catalogs. It is not always necessary to page through the physical catalog or scroll through the scanned copies. Much of the data in the catalogs was entered into an Access database in the early 2000's, and was migrated through to the Specify database.
