RDA – Delayed

Monday, December 7th, 2009

It’s beginning to seem more and more like the ‘D’ in RDA stands for ‘Delayed.’

Karen, our resident Authority and RDA Librarian tells us:

An announcement about a delay in the publication of RDA was posted on the RDA listserve:

RDA: Resource Description and Access will be published in June 2010.  While we regret this delay in release of RDA, the transition from publication of AACR2 as a printed manual to release of RDA as a web based toolkit is a complex process with many interdependencies.

The updated text of RDA incorporates recommendations from constituencies and other stakeholders approved at the JSC meeting earlier this year.  The revised text has been successfully loaded into the RDA database.  The product is currently undergoing thorough quality review and testing in preparation for release.

We recognize that customers and prospective users of RDA need reliable and timely information for planning and budgeting.  We are confident that this revised deadline is a realistic target for publication of RDA.

Pricing and purchasing information will be introduced at the time of the ALA Midwinter Meeting, 15-18 January 2010.

Help! New Cataloging Code is Coming… RDA Helps

Monday, November 30th, 2009

Karen, our librarian and resident RDA expert let me know about a little update on the RDA front. I think it’s well worth your time to take a look, especially if you’re feeling a little stressed about RDA.

The last I heard, RDA is still scheduled to be published this month, and I know many are anxiously awaiting it.  (Either in excitement or trepidation!)  I saw this link to slides from an update about RDA given to the California Library Association Annual Conference on November 2.  It not only gives a good overview of RDA and its underlying models, but goes over the new data elements in RDA and some basic differences between RDA and AACR2 with examples to illustrate them.  There are also helpful links.  I really love the title:   “Help!  The new Cataloging Code is Coming!”  This presentation will surely help.

Adding New Services

Monday, November 23rd, 2009

Hello and welcome to our friends in the Library world. We hope that this week sees you with much happiness and joyous thanksgiving!

You may have noticed a few subtle changes occuring over the last few days and weeks. Slowly this site is changing from the Authority Control blog to the Automation Services blog. Why are we making these changes? Because we’re making a concentrated effort to make your lives easier by offering more solutions for a greater variety of needs.

We’ve already talked about one of these services, Marcadia, here. Nate Cothran, the Vice President in charge of Automation Services explains a little bit about some of the other new services and how they can help you.

Machine-Upgrade

Have bib records with a brief amount of information?  Are they good enough to keep but not bad enough to discard?

Backstage Library Works can upgrade your brief bib records against full MARC records from Library of Congress.  The matched records will replace your brief records, bringing them in line with current MARC21 standards and AACR2 formatting.

We have many different options for you to consider when upgrading your brief records.  What’s important is returning matches that enhance your collection.  Try our FREE Records Test today and see if the Machine-Upgrade service is right for you and your bibs.

Deduplication

Have a set of records that need to be consolidated?  Just acquired new records to add to your existing database?

Backstage Library Works combines your records into one manageable database.  Deduplication merges your duplicate records into one match.  Have holdings fields you want to also merge with the matched record?  We can retain any field you specify and even move data around based on your instructions.  Backstage Library Works lets you decide how strict or lenient the match criteria should be.

You receive a cleaner database, with all of your data intact and the peace of mind that comes from knowing another project can be crossed off of your list.

Custom Services

Need to rearrange the data within your records?  Have a subset of records that could benefit from a quick fix?

Backstage Library Works offers the ability to work within your expectations.  The way you want to modify your records is the right way and we can make that happen for you.  With our expertise in your corner, you no longer have to worry about when you will have the time to change your records.  We make the time for you and return it when you need it.

At Backstage Library Works, we don’t ask, “Why do you want to do that?”  We ask, “When can we make this happen for you?”

Genre Terms and the GSAFD List

Tuesday, November 17th, 2009

Judy Archer shares with us her insight on genre authorities and GSAFD.

Ahhh genre terms … what a subject is, versus what a subject is about.  The necessity for this distinction seems obvious, doesn’t it?  If I want to find poetry written by Robert Frost, I wouldn’t necessarily want to weed through all the works written about his poems, would I?  The more logical option is to access only his actual poems.  Yet for a long time I had no choice, for genres were considered part of the general subject access.

 

As time went by, the library community saw the need for a distinction and recommendations were developed for a national standard.  This standard provided guidelines for developing genre access as well as subject access for fictional works, humorous works, drama, poetry and folklore.

 

To accommodate this effort, the “Guidelines on Subject Access to Individual Works of Fiction, Drama, etc.” 2nd edition was published in 2000, and this came to be known as the GSAFD.  In chapter 1 of that Guideline was a list of 153 genre terms, and in 2001 the Association for Library Collections and Technical Services (ALCTS) developed MARC21 authority records for these 153 terms.  The source file is located at Northwestern University, but OCLC has a link to the terms and their full authority records, which can be accessed at the following link:

 

http://alcme.oclc.org/gsafd/OAIHandler?verb=ListIdentifiers&metadataPrefix=z39_19

 

If you would like to know more, The ALCTS discusses their creation of the authorities here:

 

http://www.ala.org/ala/mgrps/divs/alcts/resources/org/cat/marc21authority.cfm

 

Discussions continue about the formulation of genre terms, and the Library of Congress began their own ambitious project in 2007 to formulate authorities for genre terms.  They started with Moving Images, but they have also moved on to additional categories such as:  Cartography, Law, Religion, Literature and Music.   They have a timeline and commentary about the project which you can find here:

 

http://www.loc.gov/catdir/cpso/genretimeline.pdf

 

Many libraries will use terms from the GSAFD list, the Library of Congress authorities, or other thesauri.  If you plan to use the 153 GSAFD terms in your catalog, they are handled by way of a 655 field using a second indicator of ‘7’ and a subfield $2 with the term ‘gsafd’.  This clarifies the thesaurus you used.  Here are examples of how both GSAFD and LC terms are entered in MARC21:

 

From the GSAFD list:

            655_7  $aEpic poetry.$2gsafd

 

From the LC subject headings catalog:

            655_0  $aRoad films     [or]     655_7  $aRoad films.$2lcsh

AAT – Art & Architecture Thesaurus

Tuesday, October 27th, 2009

Many people know what the Library of Congress Authority Record Database is and how it can help their library. But what do you know about the other large authority collections? Nate Cothran, Product Manager of MARS Automation Services and expert on the Art and Architecture Thesaurus (AAT) sheds a little light on it for us:

The Art & Architecture Thesaurus (AAT) is a collection of 131,000 authority records about the visual arts and architecture maintained by the Getty Institute. Though the AAT is updated every month, the licensed version—which Backstage uses—is sent out once annually.

Within the authority record itself, the AAT entry lists the main heading in the 155 tag:

001 __ 300015529
155 __ $abird's-eye views$B(<views by vantage point or orientation>, views, 
<visual works by form: image form>, <visual works by form>, <visual works>, 
Visual Works, Visual and Verbal Communication, Objects 
Facet)$I1000015529$TDescriptor$GN/A$HCurrent$VUndetermined$L70052/American 
English$AN/A$ON/A$8300015529.1

The 155 $a is the part of the heading that will be reflected in your updated bib heading:

 655 __ $abird's-eye views

I can see what you’re thinking on this: How is it that the authority’s 155 above contains so much more information than the bib’s 655 field? Sometime in the last year, the AAT authority records began including an incredible amount of reference points & additional information encoded into capital-letter & numbered subfields. Unless your system is able to incorporate this extra data, the pertinent information you likely prefer to retain resides in the main (lower-cased) subfields.

In order to bring the authority records received from AAT back into a more manageable structure, Backstage can remove all of the capital-letter subfields as well as the numbered [0-9] subfields. This makes the loading into your system error-free in case your system balks at the extra subfields it has to somehow categorize on the fly.

So this revised authority heading:

001 __ 300015529
155 __ $abird's-eye views

Now matches cleanly and updates easily within your ILS system.

At least now you’ll know what to look AAT in your Art & Architecture Thesaurus authorities.

Authority Control Interest Group (ACIG)

Monday, October 19th, 2009

Authority Control Interest Group (ACIG)

About twenty years ago I attended my first American Library Association Conference.  I was relatively new to the library world and really looking forward to the ALA experience.  I had heard so much about the great meeting being held about all topics known to “Library” Mankind.  It was a long time ago, and I don’t remember the details of any of the meetings I attended with the exception of one.  It is as clear today as it was some twenty years ago.  I stepped into a rather large conference room, standing room only, as I recall.  There was a panel of experts placed at the very front of the conference room on a stage with microphones for each and pitchers of water placed strategically on the table for all to share.  There was a standing microphone placed in the middle of the isle and as the panel completed their discussion, an anxious group of librarians lined up behind the microphone to say their piece.  Soon an angry tirade of heart felt opinions emerged.  I don’t remember the exact discussion, but I do remember it had something to do with the creation of an authority control record for “nuns”.* I was amazed at the passion and at times anger expressed in the varying opinions.  I remember thinking to myself, “What is wrong with these people!

That, ladies and gentlemen, was my first introduction to what we know today as the ALA Annual Session of the Authority Control Interest Group.  Oh yes, there is great passion in authority control.

So, you may ask: what is the Authority Control Interest Group (ACIG), and why should I care?    We will start with the group’s history and mission.  The ACIG was established in 1984 by Barbara Tillett.  Its original name, “Authority Control in the Online Environment Interest Group” highlights the original purpose of the group, which was to bring about awareness to technical service librarians who were moving to the online environment. At that time most of the existing ILS systems had not configured authority control into their ILS systems.  In 2006 the name was shortened to, “Authority Control Interest Group”.   The goal of the group was to provide a forum for discussion of issues related to authority control for online cataloging.  The forum is used to raise the level of awareness on authority control issues and to encourage ideas for new approaches to authority control.  Each year officers are elected to coordinate overall activities of the interest group.  The group is co-sponsored by the LITA and ALCTS divisions of the American Library Association.  A program is presented at each ALA conference.  The programs typically address what is new in the world of controlled vocabulary.  A representative for the Library of Congress typically gives an update of what is going on with authority control within their organization.  OCLC usually sends a presenter to update the library world on OCLC involvement with authority control.   The rest of the panel usually consists of people who are either experts in an area the group is focusing on for that particular meeting, or people who have done research in the area that the group is focusing on for that meeting.  The sessions are usually well attended.  You can expect several hundred for the summer session.

Upon completion of the presentations, the ACIG group gathers to have a business meeting.  All who are interested are invited to attend.  In this meeting officers are elected and the next conference presentation is discussed.  Over the next six months, the Vice-Chair works with the library community and the ACIG committee to put together a presentation for next conference.

I have been involved with the Authority Control Interest Group for the last four years.  I found it a very good vehicle for keeping a pulse on the authority control world.  The group is always looking for volunteers and welcomes new members.  For more information on the ACIG please visit their wiki site at http://wikis.ala.org/lita/index.php/Authority_Control_IG

*Out of curiosity, I looked to see if there was a heading for nuns and there is.  It is listed below.  For the life of me, I don’t remember what the debate was about!
