Changes to the National Library Catalogue
The Library’s Catalogue has just had a major upgrade. We’ve changed platforms, but don’t worry – all the records and functionality you’re used to are still there.
Important: Records on this site have a link to their National Library Catalogue page (where it says See original record), but these links haven’t been updated yet. To find the record, you’ll have to search again from the Catalogue homepage.
We’ve also added more! You can search Index New Zealand in the same place, as well as many of the online journals we subscribe to.
Make sure you change your bookmarks!
There’s a lot happening in the background as we make everything work properly, so until late October you won’t be able to directly access digital content in the National Digital Heritage Archive.
Library staff in the Reading Room will be available to help you access the digital collections in the meantime.
Links in National Library bibliographic records to items in the NDHA
There will be an outage in direct access to unrestricted digital content housed in the National Library of New Zealand’s National Digital Heritage Archive (NDHA), and the National Library will need to provide refreshed files of bibliographic records with links to unrestricted NDHA content as we move from Voyager to ALMA.
The digital publications we collect under Legal Deposit are housed in Rosetta, an Ex Libris application.
Each monograph and each issue of a serial are treated as a separate Intellectual Entity (IE) in Rosetta.
Each IE in Rosetta has a delivery URL using a Rosetta-generated Identifier (PID) for that IE.
So, each individual issue of a serial will have its own delivery URL. For example, the serial publication Tabs on Travel (for which we have 1732 issues), will have 1732 IE PIDs.
The descriptive records for this content are most often not a one-to-one relationship. It is for most monographs, or one-time publications. For serial publications, there is a one-to-many relationship (that is, a serial record will describe the entire run of the title).
Moving from Voyager to ALMA
The integration between Rosetta and Voyager was built around the Voyager BIB ID. While the Voyager Bib Id will be available in ALMA this is legacy data. All existing and new records will have a MMS ID assigned (this is the ALMA equivalent to the Voyager BIB ID).
As a result of this, we effectively have to re-build the Rosetta/ALMA integration based on the new MMS ID.
This entails de-linking from the current Voyager system and then re-linking to ALMA. Due to the size of the Library’s digital collections this will unfortunately take some time to complete.
Implications for the Primo discovery application
The Library developed a Content Aggregator to allow for display of the IEs available for any bibliographic record, including material where there were multiple issues in the NDHA attached to a single Voyager record (most often for serial titles).
The Content Aggregator was also based on the Voyager BIB ID loaded into Rosetta.
While the digital inventory of an Alma bibliographic record does hold all of the IE PID references for all the IEs associated with that bibliographic record the aggregation of that content for delivery is managed by the “View-It” functionality within Primo.
The “View-It” tab in Primo uses a publishing inventory ID generated by Alma and Primo. This ID is only generated at the point at which the digital inventory is created. The digital inventory can only be created once we have completed the synchronisation process between Rosetta and ALMA.
We expect the synchronisation of Rosetta and ALMA to be completed around mid-October.
We are looking at a potential workaround for maintaining embedded links to NDHA content in external systems using the migrated Voyager BIB ID in ALMA and will be in touch as soon as we have ascertained the viability of the proposed approach. This will not be a long-term solution as more content is added to the system against MMS IDs in ALMA.
We are very aware that this is an unsatisfactory position for all those libraries linking to digital content from the National Library’s digital collections and we will be working very closely with our vendor to ensure that this does not happen again.
