Participated in the second of the Nexpress cataloger conference calls. Sherrie had asked if I should be doing this or perhaps Mary. I think Mary should start to be involved in this. I'm going to talk to her about participating in the next meeting. Mostly we've been discussing the various issues relating to the way records from our local catalogs have or have not merged in Nexpress. Basically, Williams is getting a LOT of non-returnables requests because the records they have for e-journals have the print ISSN in them, which is what the A&I vendors use to pass OpenURL requests in most cases. Williams had specified getting the print records as first choice from SerSol, whereas Bates, Bowdoin and Wellesley (maybe Colby too) specified electronic records. The result has been that Williams records in Nexpress are more likely to match holdings in the Non-returnables module.
The other issue is that our records are not merging because some of us who get electronic records as a priority from SerSol, are getting the print ISSN in a |y of the 022. The |a has the e-issn. Because Williams and Wellesley didn't have load table training at the time of their load, they had to use the basic m2btab.b loader, and had to ask SerSol to prepend a 1 to the 001 SSJ number, so that it would be recognized by the load table as a valid 001. Why they couldn't have III change the m2btab.b table to accept alpha characters, I don't know, though it may have to do with possible "random" overlaying of non-matching records that happened to have the same 001 even though they came from different sources, OCLC and SerSol for example.
Confused yet? Well the way the matching algorithm works in InnReach is that it looks to match on the 001 and if it finds a match, it merges. If it doesn't find a match, then it checks the 020 field |a (ISBN), and failing a match there, it checks the 022 field |a. So as a consequence you can see that we have three different records for some electronic resources:
search American Economic Review (Online), and you'll see what's at issue. One record with Williams and Wellesely, one with CBB, and one for Northeastern (who uses TDnet).
We are looking into various ways to fix this, including:
-- doing the changes ourselves via global update [con: we'd have to do this every month]
-- asking SerSol to strip all ISSN's from the Conser MARC records we receive and load new ISSN data from their database (print to be mapped to |a [my choice, since we're paying them, but we'd likely have to reload a LOT of records, but they would change this in our profile and we'd never have to deal with it after this fix, "famous last words"]
-- waiting til the format-neutral ISSN is developed by the ISSN agency... [Chris (Will) and Sandy (Well) will report back from NASIG on this... it turns out it's not coming til the Fall of 2007 at the earliest]
To see an example of the fix we're proposing
search for 19th Century Music and select the first record (the one that says it's print format)... Don't worry about why the electronic links aren't showing up from our record; it's been reported to III. If you select MARC display, you'll see that our SerialsSolutions records did merge with this, once we manually changed the records. Indeed, the SerialsSolutions electronic record went away totally, and because of the print ISSN, the holdings merged with the actual print periodical record. This would mean that we'd have a one-record approach in Nexpress, but not in our own catalogs. And not in Maine Info Net. At any rate, we have to be mindful of how any changes will affect our users. This record will be ONE LONG RECORD! Click back in a week or so to see if III has fixed the electronic link display issue. You'll see what I mean.
Seems like I'm the right person to be thinking about this for the Library, since I'm doing the loading of the records, and likely to continue doing that for a while. We've not even begun to discuss the EEBO mess (more non-matching records...) ... next conference call is Tuesday.
