Authority Control - Can I haz it?
I am still a newbie to cataloguing and therefore I am fairly positive that I am still wandering around the darkness of information services, barking my shins on the bibliographic furniture.However, I have been working on the addition of authority headings for items in two separate collections, which has been both super interesting and a little bit of a baptism of fire.Â
The use of authority headings is all about Authority Control. As far as I understand it, these headings at the authorized by the Library of Congress as an established term to use. It is a control vocabulary that is agreed upon, verified and has the ability to link parts of the collection together, making it more useable. This is a bare bones summary, I am sure that this can be more fulsomely summarized, but these are the key points that I have been introduced to. Â
The 'baptism of fire' comment is less about having messed up the headings themselves (I was started on a collection that was pretty transparent- adding public garden name to items within SB466. Otherwise known as books about gardens) but more about important they are and therefore the best way to use them (and by best way, I mean in the context of this information service and it's users- maybe). Â
I don't think I appreciated just how cool these additions actually are- the Longwood's catalogue is definitely in need of more authority heading such as this to make the catalogue more usable. But it's the combination of local headings and OCLC heading that really starts to blow my tiny little mind when cataloguing items.
I have already mentioned my project in added heading to the SB466 part of the Library's collection, which is just the 610 (Corporate Name) or the 651 (Geographic Location) information to the existing record, all of which exist already on OCLC and which I access and export through the Connexion client. I find the names of the gardens in the table of contents, do a search, mark for export, import to the ILS, add to the MARC record and voila! All these generic and obtuse titles, such as 'Gardens of Europe', are now infinitely more findable and useable for research.
My other project, however, is a little more complex, as it is dealing with the archival pamphlet collection that has not only an important research use, but also an organizational context. This means that some of the headings I am using have been generated locally, as these bibliographic terms are only relevant to organization and are therefore not monitored by the Library of Congress. This means that I have to search for headings not only in Connexion, but also in the ILS. And the ILS does not have the same maintenance as the Library of Congress (naturally, because time and resources). So this work turns into a find the heading, make sure there are not multiple options, ascertain ether its a full record and then allocate accordingly to the record, making notes of any changes that might need to be made to the ILS.
Because the things about having a controlled vocabulary is that it only works if it is actually controlled. And it's hard to achieve this, if there are 5 variations of the same heading and these have not been linked together in a way that would successfully retrieve all the items. Which is, understandably, a bit of a nightmare. But a nightmare that I beginning to understand more fully. I am pretty certain that this is cold comfort for the serious cataloguers out there. I can mentally here you kiss your teeth over these processes. But the database is maintained by volunteers and interns of various skillsets, interests and understanding. There are few individuals who, having been names consistently on some pretty borked headings, I would like to sit down with over a beer and give a stern talking to. Â
This is soon be another interns problem, however, as I am wrapping up at Longwood and am looking forward to doing more controlled vocabulary work at Monash Uni. I don't know whether I can make the assumption that a University will have more effective local databases, but it seems likely. I do hope that my understanding and experience of authority control will increase because, gee whizz, it sure it useful.
