As a librarian my suggestion would be to combine all subject headings into one field and allow some sort of check against the authority file (ie. do you want to accept it or not if it does not match an existing subject heading). This would allow the librarian to reject sears headings if you use LC etc. Alternatively allow something in set up that allows you to decide at the start if you will accept only the fields which contain sears headings or only the fields that contain LC headings and ignore the others. I know nothing about programming so I don't know how easy this is to do - or if it fits in with what you are trying to do Tonnesen Steve <tonnesen@cmsd.bc.ca>@lists.katipo.co.nz on 13/12/2000 07:19:19 Sent by: koha-admin@lists.katipo.co.nz To: Koha Open Source Library System <koha@lists.katipo.co.nz> cc: Fax to: Subject: [Koha] MARC Records MARC records have an astonishing amount of detail, both in terms of data about the book, as well as ways in which the data can be described. I'm wondering how I should handle the first difficulty: subject headings. MARC records have several different entries for subjects: 650 Subject added entry -- Topical term Subjects like Mammals, Nuclear Warfare, Law, Alcohol, Child Welfare, etc. Appears to be the most common type of subject entry, at least with my data. 651 Subject added entry -- Geographic name Subjects like Canada, Rome, Moon, China, British Columbia, etc. 600 Subject added entry -- Personal name Subjects like Plato, Helen Keller, Charlemagne, etc. In addition each subject entry also specifies a source "system" such as Library of Congress Subject Headings or Sears Subject Headings. Obviously Koha doesn't have this complexity of subject headings, and probably doesn't need it, but I'm suspecting that we probably don't want to mix subject headings from different cataloging systems. Any possibility of adding a field to bibliosubject to specify a subject heading system used? Also, should I be adding any subject headings gathered from MARC records to the catalogueentry table (which I assume is used to deter librarians from adding new, conflicting subject headings like "Cows" and "Bovines"). I also have a request. Could people send me some samples of their MARC records so I can do some sanity checking? A lot of my MARC records are not from "formal" sources, but were hand entered by the librarian here. I'm also curious to know how librarians typically use commercial CDs of MARC records. Do they import all of the records into their library system at once, or just import records for books they hold? How are the MARC records typically stored on a CD? Is it just one big file full of MARC records?
