Abstract:

Web pages cited with personal author identification in 12 longer Web bibliographies and a collection of 19 shorter Web bibliographies were investigated. With one exception, the personal author names could be matched in the visible text of the great majority of pages. Metatags (both for authors and for descriptions) and page titles rarely added any author information. In some cases, frames or inline graphics appeared to be the sources used. Somewhat more frequent probable sources were linked pages, such as home pages.
