There has always been some confusion on whether or not certain MARC fields should be removed from incoming copy. There are lots of fields that this and many other libraries don't actually use or even display that we nonetheless keep in our records, but also some that are misleading to the public and need to be removed. There are also fields that Sirsi will remove for you, so long as you import the record through Smartport. These fields are known better as "junktags" and refer to a list of such tags that the ILS Librarian maintains at the system level. There is a list of these on the Symphony Tools section of the department's public Website. The list below is to guide you in the removal or replacement of certain MARC tags that come in with copy from OCLC.

CAVEATS

015

National bibliography number


These are the equivalent of the LCCN for libraries outside of the U.S. & Canada

016

National bibliographic agency control number


These are the equivalent of the LCCN for Library & Archives Canada

019

Superseded OCLC #


This is where OCLC places their control number for records that have been de-duped out of existence; these are now also in 035$z

024

Other standard identifier


This is used for UPC codes and other standard numbers that are useful for searching (and they are indexed!)

052

Geographical classification


These represent the LC class number for the geographic area of the work, minus the "G"

055

LC call number assigned by a library in Canada


Except for some Canada specific class numbers, such as the PS8000-9000 and FC, these are perfectly good LC call numbers

060

NLM call number


These are useful for keyword searching, to find an LC call number on another record when your copy has only an NLM call number

070

NAL call number


These are actually LC call numbers assigned by the National Agricultural Library,and can often be used to help you classify a work

082

Dewey call number


These are useful for keyword searching, to find an LC call number on another record when your copy has only a Dewey call number

596 & 599

Local notes fields


Holding library (596)  and most recent issue received (599). The 599 field should be deleted if you are receiving the final print issue of a serial.

918

CatKey


This is the system-assigned unique number that identifies this record in Endeca static URLs. If there is just one, do not delete! If there are multiple 918s, you may delete all but one, however, if they are not all the same, contact Lynn/Rob L./Tessa/Dawn so they can help you identify the true catkey

919

DRA control number (DBCN)


These are leftover from our previous ILS and have no real utility anymore, except for really old record printouts that accompany materials that have been awaiting cataloging since prior to 2003. In this case, the DBCN is the only connection you have from the printout to Sirsi
