Wellesley is an index to the authorship of articles, and a bibliography of articles written by each contributor, and using each pseudonym. Citations of evidence are provided to support attributions of authorship, along with brief biographical and vocational details. 45 important monthly and quarterly titles are included, covering the period from the beginning of the Westminster Review in 1824 to the end of the century. The exception to this is the Edinburgh Review, which is indexed from first issue, in 1802. Wellesley does not index poetry.
