MARCIVE Now has More Than 20 Subscribers to Comprehensive Notification Service (CNS)

In February 2017, MARCIVE released a new product that helps libraries keep a better handle on how authorities processing is performed in their ILS or LSP.  Over the years, customers had commented how once an initial backfile authorities processing project was completed and Standard Notification Service was begun, their systems didn’t always do a good job using the monthly updated authority records to revise the associated bibliographic records.  It was difficult to pinpoint why and in what cases an access point would not be updated, even though the proper information was present in the revised authority record.

Comprehensive Notification Service retains the bibliographic as well as the authority records, and periodically refreshes them using the newest authorities files on either a quarterly, biannual, or yearly frequency.  Only the bib records that reflect a change are provided, along with new/changed/deleted authority records.

Access points that were previously unmatched are updated when matched to new authority records through CNS.  Any new fields reflected by new policies in RDA, and continual improvements to MARCIVE processing are also seen.

The number of records changed is typically less than 5%, but different factors can affect the statistics:

–A change to a prolific access point is released by LC, so many records are affected.

–Changes in a profile option.  For example: A library that didn’t ask for processing of FAST access points at the onset and later requests it will see a large increase of changed records.  Or a library that decided to have URI identifiers added to their processing asked us to add that free option with the next update.

Subscribers can send in both bib and authority deletes before the next processing to keep the history files current.

If a library decides they don’t want to track deletes because they weed a great deal, or don’t have the staff to keep up can send their entire database to replace the current history and use that as the input file.

Although CNS was created with Ex Libris Alma members in mind, there are 10 different systems among customers of public, military, and academic libraries of various sizes.  Both public and academic consortia are represented as well.
