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!

We Need Your Input!

Thursday, September 10th, 2009

Judy, one of the project managers would like opinions from multiple librarians on a question we are facing right now. Here’s what she had to say.

Hello Everyone, we are looking for feedback from our community:

MARC Proposal No. 2008-06 requested that $x ISSN’s be allowed in 8XX fields (http://www.loc.gov/marc/marbi/2008/2008-06.html) and the proposal was approved by Library of Congress on October 2, 2008.  Just recently OCLC has decided to begin allowing $x too (see their July 2009 Technical Bulletin 257 found at:  http://www.oclc.org/support/documentation/worldcat/tb/257/default.htm.

With LC’s switch from 440 to 490 and our programming changes to accommodate this, many of you are now getting $x ISSN subfields in your Bibliographic 8XXs.  This has been causing some concern and at least in one scenario, it creates a problem situation as follows:

original bib headings:
490_1 $aSTI/PUB ;$v1343
490_1 $aSafety reports series,$x1020-6450 ;$vno. 58
830_0 $aSafety reports series ;$vno. 58.

after processing:
490_1 $aSTI/PUB ;$v1343
490_1 $aSafety reports series,$x1020-6450 ;$vno. 58
830_0 $aSafety reports series ;$vno. 58.
830_0 $aSafety reports series,$x1020-6450 ;$vno. 58.

The resulting 830s happened this way because the 8XXs must link up with 490-1’s.  The system assumes the first 8XX belongs to the first 490-1 so it retained “Safety report series ;$vno. 58.”  Since it “thought” there was no 8XX for the second 490-1 an 8XX was created for it.  Unfortunately it was the first 490-1 that was missing a linking 8XX.

What is your practice regarding 8XX $x?  Since this is now an allowable subfield and we follow LC procedures, what will this do to your system?

Your feedback would be very welcome and much appreciated. Feel free to comment on this blog or talk about it on our Forum at:  http://ac.bslw.com/community/forum/viewtopic.php?t=34

Thanks,
Judy

Backstage Library Works Automated Services

Monday, August 31st, 2009

You may have noticed that we’ve recently changed the name of this blog from MARS Authority Control to MARS Automation Services. Why the change? I’ve asked our Chief Operations Officer of the Utah location, John Reese, to explain why. Here is what he had to say.

***

Before the purchase of MARS from OCLC, Backstage Library Works ran several bibliographic automated products.  These services include Non-MARC or Brief MARC Record Upgrades (Machine Matching), Deduplication and Consolidation of bibliographic data, Union Database creation, Marcadia and Custom Programming.  Prior to this week, these services were run independent of the MARS 2.0 Automated Authority Control Service.  Backstage is happy to announce the consolidation of all of the above mentioned services and MARS 2.0 Automated Authority Control under one division to be called, “Backstage Library Works Automated Services.”

We found that there was a lot of overlapping in client needs involving authority control with the above mentioned automated bibliographic services.  All of these services require technical knowledge of the automated process.  At Backstage we are now sharing this valuable resource under one umbrella, Automated Services.  We look forward to having one department work with your sales representative in offering the most efficient automated solution for you.  Below is a list of all of the services under our newly formed Automated Services department.  If you have question about this change please contact John Reese, jreese@bslw.com.

MARS 2.0 Automated Authority Control:

MARS 2.0 service is one of the oldest and most reliable automated authority control offerings on the market. With our new system upgrade introduced in 2008, managing your authority records has never been easier.  MARS 2.0 offers name and subject authority control based on the Library of Congress name and subject authority databases (and other available National databases like MeSH, NLC, etc.).  The authority control process standardizes name, subject, series and Uniform title headings.

Automated Machine Matching:

This service offers several options to upgrade non-MARC or brief MARC records to full MARC bibliographic records.  This process searches electronic records against Backstage Library Works database and the Library of Congress Bibliographic Database to return a full standard MARC record.  There are over twenty million records to match against in this database.

Automated Deduplication:

Backstage Library Works offers a deduplication process that consolidates bibliographic or authority records in a library’s database(s).  This process is performed according to the profile specifications of the library and is often used when a library or a library consortia is forming or adding new libraries.

Union Database Creation:

Library consortia or library districts often require a central database for their consortia to work from. Backstage helps libraries create Union Bibliographic as well as Union Authority databases.

Marcadia:

Marcadia is an automated batch copy cataloging service offered jointly by OCLC and Backstage Library Works.  This product finds, evaluates and delivers catalog records from OCLC WorldCat.  It is based on search records you supply from your local system and a selection criterion you provide.  Marcadia selects matching records from WorldCat and delivers them to you.

Custom Programming:

It has been a long standing Backstage Library Works’ tradition to customize our services to the needs of our libraries.  Many libraries require special programming to accommodate either earlier cataloging practices that no longer meet current standards and need to be changed or special programming to create unique processes for their library.  Backstage takes pride in its ability to accommodate these special needs.

Basic Authority Control Terms for Novices

Tuesday, July 7th, 2009

Authority Control is a specialized subset of library science and has it’s own unique vocabulary. To help librarians and administrators who may be dealing with authority control for the first time we’ve created, and are continuing to create, resources for both authority novices and experts. Today, we’ve asked our resident Authority Librarian to give us a brief and basic overview of Authority Control. We hope it helps.

Some basic authority control terms:

Authority control

The term used in library and information science to refer to the practice of consistent use and maintenance of the forms of names, subjects, uniform titles, etc. used as headings in a catalog. Authority control fulfills two important functions.

1)  It enables catalogers to disambiguate items with similar or identical headings.

2)  It is used by catalogers to collocate materials that logically belong together, although they present themselves differently.

Authority control can provide the underlying structure of the catalog when this process is used to create links between bibliographic records and the authority file.

Authority work

The process of determining the form of a name, title, or subject concept that will be used as a heading on a bibliographic record; determining cross references needed to that form; and determining relationships of this heading to other authoritative headings.

Authorized Heading

The form of an entry, i.e., the word(s) or phrase(s) chosen to provide an access point to the bibliographic record in the catalog or database.

Cross-reference

An alternate heading which directs the user to either the established form of a heading or to related headings Through the use of see and see also references, authority control creates a syndetic structure that guides the user to the materials sought.  This structure forms the pillar of authority control and makes possible efficient access to resources

See Reference – variant forms from the chosen, or authorized form of the heading.  They are used to lead the searcher to the proper form of the heading.

See Also Reference – Related form of a heading that is also an authorized heading.

Authority record

A record which shows a heading in the form established for use in the catalog; lists the cross-references to be made to and from the heading, cites the sources consulted in establishing the heading, and includes any other information that would be pertinent to the heading and its use.

Authority file

A set of authority records listing the chosen form of a heading and its appropriate cross-references. Types of authority files include name authority, series, and subject authority files

Library of Congress file are widely used.  They have separate name and subject files, but they are indexed together for searching at http://authorities.loc.gov/ In addition to using a national authority file, individual institutions may have local authority files.

Global change

The ability to change every occurrence of a specified string of characters in a catalog, usually by using one command to change all representations of a heading from one form to another form.  This is facilitated by actually linking the authority headings to the bibliographic records.

We have even more resources, including an extensive and growing terminology page on our Wiki.

Juvenile Subfield Additions

Monday, June 8th, 2009

Adding a Juvenile Subfield $v to your Library of Congress Heading

Children’s subject headings are a separate file within the LC subject file. They are designated by a second indicator of 1 in the 650 tag. The adult representation found under Library of Congress Subject headings uses a $Juvenile qualifier. The LC Children’s authority file contains just over 950 authority records.

In the automated authority control world many of our libraries are interested in changing all of their children’s subject headings to their Library of Congress equivalent.  We have always had the ability to search these children’s headings against their adult equivalent.  Recently, our clients requested that we add a juvenile subfield $v at the end of a heading that we flipped from Juvenile to Adult.  That was easy enough to do we simply added a $vJuvenile at the end of the tag once the heading was flipped to an adult heading.  However, this still did not adequately define the type of juvenile subdivision we wanted to represent the heading.

We knew that there were fixed fields within the bibliographic record that more precisely defined the type of Juvenile book we were looking at.  What we decided to do is base the juvenile designation on these specific codes.  If the bibliographic record is a book format (leader/06 = ‘a’or ‘t’) then we check byte 33 of the fixed field to determine what type of juvenile heading this is.  There are fourteen different characters that define the Juvenile book from Comic Strips to Speeches.  However, there is not a valid subfield $vJuvenile …. for each representation.  What we decided to do was translate the ones that did have a valid representation to that heading.  For instance if byte 33 was a ‘d’ we created the juvenile heading $vJuvenile drama.   The following charts indicate what heading are assigned to what code in byte 33.

= “1” : add “$vJuvenile fiction”
= “d” : add “$vJuvenile drama”
= “h” : add “$vJuvenile humor”
= “p” : add “$vJuvenile poetry”

All headings that did not have a valid subfield $vJuvenile representation in byte 33 were defaulted to Juvenile literature.

We also looked at leader byte six to determine if the bibliographic record was something other then a book and assign an appropriate juvenile designator to the headings.  For example, if leader byte 6 is ‘e’ or ‘f’ for maps we add $vMaps for children or if byte 6 is a ‘g’ and byte 7 ‘m’ or ‘v’ we add $vJuvenile films to the adult heading.  The following example illustrates what this change will look like once your juvenile headings have been converted to Library of Congress.

Examples
        Child heading:
        650   1 $aRain forests.
        650   1 $aCollies$vFiction.

        Matched LC adult with "Juvenile" description added:
        650   0 $aRain forests$vJuvenile literature.
        650   0 $aCollies$vJuvenile fiction.

For a more detailed account of subfield $vJuvenile assignments please review section 3.8 of our planning guide: http://ac.bslw.com/community/wiki/index.php5/Profile_Guide_Step_3.8

Announcing: Heading Tracker a death date fix and more

Wednesday, April 15th, 2009

Backstage Library Works is pleased to announce Heading Tracker, a much-anticipated enhancement to the MARS Authority Control Service. This enhancement is free to MARS clients using ongoing authority control services — Current Cataloging, Notification Services, or both.

In response to requests from many of our clients, the MARS team has developed this Heading Tracker enhancement to bridge the gap between antiquated and updated headings provided by the Library of Congress, when LC does not formally establish a see reference to connect the old heading to its new version.

This gap is most often noticeable in the problem whose solution we’ve long referred to as the ‘death date fix’ — where LC adds a death date to a name heading, causing a disconnect between your records with open death dates and the new authorized headings with closed dates — but it shows up in changes to uniform titles and other headings as well.

To resolve this problem, the Heading Tracker subroutine automatically generates a see reference (4XX) in your authority record, using the old Library of Congress heading. This see reference is marked as a local tag with a subfield ‘5’ and Backstage’s institution code: $5UtOrBLW. The see reference is also prefaced with a subfield ‘w’ and the appropriate coding to hide the reference from the library’s public access module: $wnnea.

An example of a see reference (4XX) correcting for the addition of a death date would look like this:
(Note that the $w and $5 are highlighted in yellow.)

As with most functions of MARS 2.0, options for the Heading Tracker can be selected in your profile. For instance, if you want to display in the Public Access module, we can do that. If you want the enhancement, but you would rather not include undifferentiated or generic headings, we can specify that, too. The standard options available for this feature are listed below.

  • Display in public access, or not. The default will be to not display.
  • Create an undifferentiated or generic see reference, or not. The default is to create the reference.
  • Clean up see references (other than a 430) by making the second indicator of that tag blank, in compliance with Library of Congress standards. The default is to not adjust the LC-provided indicator.
  • Run a second file without Heading Tracker data, directly after the first file, to remove the Backstage-created see references. This provides the connection between old and new headings when importing the files to your ILS, but removes the old references when the second file is loaded. The default is to not provide a second file.

If there are options that you are interested in that are not listed above, let us know and we’ll work to accommodate your needs.

To incorporate the Heading Tracker process on your next Current Cataloging or Notification run, please contact your MARS project manager.

The MARS staff hopes this enhancement will further streamline your automated authority control process. Your input is always appreciated. Contact us if you have questions or concerns.
