They are essential to secure a degree of uniformity in the application of the rules where a large collec- tion of great variety is being catalogued. The following statement, cover- ing the practice in the Library of Congress, is intended for the guidance of cataloguers without intrenching on the exercise of good judgment on their part in dealing with exceptional cases on their merits. It is printed to meet the requirements of the library service, and to facilitate the answer- ing of numerous requests for information from other quarters. 372046 1. GENERAL RULE Enter a periodical under its latest title, capitalizing both the initial article, when there is one, and the word following. Give in the form of notes : frequency of publication ; important varia- tions of title; successive editors; important changes of place of publication and of publisher; also indexes, supplements, etc., unless entered separately {see under headings Indexes and Sup- plements) Make added entries for editors, compilers of indexes, important earlier titles, etc. A periodical entry ordinarily includes all volumes published with continuous volume numbering (in one or more series), even though the title may vary. A publication which does not continue the volume numbering of an earlier publication is considered a new periodical, and should have separate entry. If the new peri- odical succeeds or supersedes the former, the connection should be noted on each entry. 2. TITLE The title of a periodical is frequently given in different forms on title-page, covers, captions, etc. The form used on the title- page should ordinarily be given preference in entry, and refer- ences made, when necessary, from other forms. When the covers, etc., have fuller title than the title-page, it is sometimes desir- able to use the fuller title, enclosing the additional matter in brackets, e. g. The Portrait magazine [containing sketches of prominent per- sons of the present time] If the publication has no title-pages, take title from covers, captions or editorial pages. The cover-title is to be preferred, unless the caption title is especially distinctive, or is the title best known and under which the periodical is generally quoted in ref- erence books and other literature on the subject. The statement of editors, etc., may be included in title if the periodical has ceased publication, and the same editors have con- tinued throughout, e. g. The Mining gazette, e
