New URI Enrichment Option

Written by Joan on January 15, 2021. Posted in Blog

With the focus on linked data, libraries now request that we provide the information when a bib term is matched to an appropriate authority record. We can insert the control number of the authority record or the URI of the authority record into subfield $0 of the bib record (recommended).

Example of control number in subfield $0 of a bib record:

650_0 $a Drawing. $0 (DLC) sh 85039408

If this option is chosen, subfield $0 control numbers will be added for the following vocabularies: AAT, ACP, FAST, GSAFD, LAC, LCSH, LCGFT, MeSH, NASA, NLA, Sears, TGM.

Example of a URI in subfield $0 of a bib record:

100 1 $a Kelly, Katy, $0 http://id.loc.gov/authorities/names/n88121754 $e author.

If this option is chosen, subfield $0 URIs will be added for the following vocabularies: ACP, FAST, LCSH, LCGFT, MeSH, TGM.

There’s been some documentation from PCC declaring a preference for using URIs that represent full matching access points and not partial access points as we provide.

October 2017    PCC Task Group on URIs in MARC Year 2 Report to PoCo (October 2017) (page 5)
“After careful consideration, the Task Group recommends against providing URIs that represent only partial entities of a MARC field. Faceted vocabularies provide an alternative means to represent such concepts by post-coordination. If the entire concept is to be represented as a single semantic unit within the LCSH vocabulary, in our view that becomes an issue for the maintenance agency rather than for implementers.”
https://www.loc.gov/aba/pcc/bibframe/TaskGroups/PCC_URI_TG_20171015_Report.pdf

This recommendation was repeated in a 2019 report (quoted from the 2017 report above): 09/12/19   PCC Task Group on Linked Data Best Practices Final Report (page 9)
https://www.loc.gov/aba/pcc/taskgroup/linked-data-best-practices-final-report.pdf

To date, we have not seen anything from the Library of Congress regarding community-wide adoption of these recommendations and it may be up to the library to choose to follow them or not. In response to customer inquiry, we will now insert subfield $0 when either a full or partial access point matches an authority record, or only when a full access point matches an authority record.

Which option is best? It really is up to the library.  If a library want to follow PCC stated best practices, they should get $0 URIs for full matching access points only.  However, this will result in a lot fewer added $0 subfields in their bib records and this additional information may be missed.  Unless the library is experimenting with Bibframe and the Sinopia linked-data editing environment, we suggest that the option to get $0 subfields for full and partial matches be chosen.  Since this is an ever-evolving area, this is likely not the last URI recommendation we will see from PCC.  It may well be that partial match URIs are acceptable in the future.

It should be noted that the choices a library makes for adding $0 subfields do not affect which authority records are returned to the library, as these are an entirely separate processes in Authority Match.  Our authorities processing provides authority records to the library for the fullest matching string.  If the library chooses to add $0 subfields for full matches only, they will still receive authority records for full and some partial matches.  For example, there is no authority record match for this full string so a URI will not be added if the library chooses to add them for full access points only:

650_0 $a Automobiles $x Air conditioning $z Arizona.

However, the library does get two matching authority records for this string:

$a Automobiles $x Air conditioning                          sh 85010204

$z Arizona                                                                       n  79034873

Here’s another example:

650_0 $a Personality disorders $x Religious aspects $x Buddhism

There is no authority record match for this full string, so a URI will not be added IF the library chooses to add them for full access points only.  The library will get this matching authority record:

$a Personality disorders $x Religious aspects       sh2019101837

Whether a library chooses to follow the current PCC guidelines for $0 enrichment or not, we have an option that is best for your library.

Why Convert Legacy Data to RDA: Public Libraries Weigh In

Written by Joan on November 3, 2014. Posted in Blog

Converting legacy data to RDA is a challenging idea to take hold in public libraries because of a school of thought regarding the short-lived nature of the collection. If your collection flips over every 15 years, why do anything with the legacy data?

Converting to RDA preps your data for the next generation systems and organizes your records in a layout that is easier for patrons to understand. Public libraries, in particular, have more formats than many other types of libraries, so the blanket term “electronic resource” is no longer relevant in today’s information environment. But don’t take our word for it, here is why some of our happy customers converted to RDA:

Cuyahoga County Public Library
Lori Ann Thorrat, Catalog Department Manager

“Cuyahoga County Public Library chose to convert our data to RDA for simplicity. Having our data in RDA format created a level of consistency that simplifies the configuration of the public catalog, improving our customer’s ability to find and retrieve materials. Dates are very important both for searching and sorting data.  Just having all of our publication dates in a single MARC field allows us to streamline how records display and sort in the public catalog. Because RDA is an internationally recognized standard, having our data already in RDA format will facilitate the conversion of our legacy data to Bibframe, the next generation schema for bibliographic data.”

Somerset County Library System
Adele Thoma Barree
, Head of Technical Services

“We know that we will not have our current ILS forever, and that RDA is designed to handle links and connections among all types of data.  Getting our database in the best possible shape for the future is something MARCIVE can help us with by modifying our bibs to reflect basic RDA format.  We are very glad you offer this service!”

Thousand Oaks Public Library
Stacy Gordon, Cataloging Librarian

“Legacy data is worth converting so that older materials become as discoverable as new materials, especially as library management systems and other discovery layers begin to take more advantage of the new fields for content, media, and carrier type.  Since these fields (336, 337, and 338) have controlled vocabularies, greater consistency will be achieved between older and newer records.  As well, when BibFrame is ready to replace MARC, more of your records will be ready to be crosswalked to the new metadata standard that will be more compatible with other information systems in the greater linked data world.

Library catalogs have gone through many changes, and a recent change is to the new cataloging standard,  RDA.  Among the benefits of RDA are fewer abbreviations (no more “ill.” for illustrations or  the Latin “s.l.” for “Place of publication not identified,” and many others), more relationships identified between works, entities, manifestations, and items, as well as between persons, families, and corporate bodies and these FRBR requirements, and a catalog that’s data conform better to what’s being seen in the wider world outside of libraries.  Conversion would provide for greater consistency within your catalog, and will allow users to find information more easily, with RDA’s allowance for a greater number of access points, increasing discoverability.

We had no trouble deciding to go with MARCIVE for performing the retrospective conversion of our database to RDA.  We have had MARCIVE do our authority control for 12 years, and they have been extremely fast, reliable, and with gracious customer service.”
