What is Published?
As of April 2004 we began rectifying an inconsistency in counting some conference proceedings papers (i.e. those in Nucl. Phys. Proc. Suppl., eConf, APS Conf. Proc., and a few others) that were being counted as published for the purposes of the citation summary. We no longer list conference proceedings as published where possible. These papers are still counted in the first column, but do not show up in the published column in the citesummary format. This decision was made on the basis of common usage in the community of published as synonymous with peer-reviewed.
Unfortunately, many conference proceedings are published in supplement issues of regular peer-reviewed journals. At the moment it is too difficult to distinguish these proceedings articles from regular journals. We could, of course, exclude from published all papers that appear to have been given at a conference, but since some of these are eventually published in peer-reviewed litereature, this seems wrong. We would prefer to identify the volumes that contain conference supplements, and exclude them individually, however, this is not an easy task, both to identify the volumes, and to allow our system to take this into account. Let us know if you have a suggestion regarding our procedure here, but for the moment, these supplement proceedings articles appear as published.
Finally, of course, there are a few conferences that have standards that are higher than those of some journals. We recognize this, but make no attempt to judge or rate these conferences as peer-reviewed.
In summary, if your conference paper appeared in a serial publication entirely devoted to conferences, it will not be counted as published. If it appeared in a special issue of a regular journal, it is currently counted as published, until we can work out a better system for identifying these.
Note that you can search for published papers using TC=P or type-code=published or the older method of SCL or PS = P or S. The first method is better for newer papers. The latter method is faster for most papers, but is harder to remember
