The thing with "volume" and "issue" is that you really want to know the order, and when you get into complex journal enumerations it can get very hairy. So Z39.50 has: Level Caption Enumeration I.e. level=1,caption=v.,enumeration=3 for "v.3" when volume is the first (highest) level If you want you could also spell out volume somewhere, but then you have to learn the correct terminology for every language that you are going to encounter. So for a journal in English you could have: level=1,caption=v.,enumeration=3 level=2,caption=n.,enumeration=12 And in German it would be level=1,caption=Bd.,enumeration=3 level=2,caption=T.,enumeration=12 This allows you to do things like: level=1,caption=n.,enumeration=324 level=1,caption=v.,enumeration=56 level=2,caption=pt.,enumeration=B level=3,caption=n.,enumeration=7 It's very flexible, and you are maintaining the order explicitly which is what will help you link to someone else's statement which might read: 56(B)7. And your citation in German can link to the same citation even if one party has chosen to "translate" the captions. Page numbers need to be given their own data element, and as I said before you need to specify whether you just have the starting page number or whether you have a range. This disambiguates a page statement like "17", which could be the start of a long article, or a single-page article. This distinction is important for requesting items from services like interlibrary loan, but is also useful for the person who wants a substantial article (or the one who is looking for a "quickie" ;-) kc ------------------------------------- Karen Coyle Digital Library Specialist http://www.kcoyle.net Ph: 510-540-7596 Fax: 510-848-3913 --------------------------------------
