I see two competing views here that we somehow need to reconcile. #1 is the view of the publisher who produces a serial publication, of which the issue is a stand-alone product. Dan's proposal seems to be focused here, as is the comics proposal. #2 is the view of the reader/researcher/academic for whom an article is a primary work whose existence in a particular issue is incidental, and to whom the entire issue, with some rare exceptions, is not meaningful, and the journal volume/number/pagination information is significant mainly as identification/location. I think the proof is in marking up examples to see what works. I could create marked-up examples but they would look very different from Dan's proposal, which seems to have gained acceptance from the group. In any case, I think that use cases are needed to test a variety of approaches. To save time, I suggest that use cases could be done in pseudo-code, as long as the results accurately reflect the proposal(s). // warning: long set of examples follows here // more examples at http://kcoyle.net/articles/ Here are some cases that illustrate the two views: #1 // full page: http://www.tandfonline.com/toc/wccq20/current Volume 51, Issue 8, 2013 Cataloging and Classification Quarterly // followed by list of articles - one example: The Road to BIBFRAME: The Evolution of the Idea of Bibliographic Transition into a Post-MARC Future Angela Kroeger pages 873-890 Access options DOI:10.1080/01639374.2013.823584 Published online: 05 Sep 2013 Citations: 0 Article Views: 482 #2 // as search results; how these look in different systems // varies quite a bit, but generally has the same // info 1.

It may even contribute to inter-regional disparities as a result of these events. To promote sustainable development, this study offers a case study of developmental planning in Chiayi, Taiwan and a review of the relevant literature to propose a framework of social vulnerability indicators at the township level. ... // articles as cited or included in a bibliography, same // article, different formats APA: Neyman, A.
