The catalog should be kept as simple as possible in its essentials. Conciseness of title, brevity of treatment, and above all clearness, must always be borne in mind. Sacrifice library school rules if necessary. Let there be no hesitation in enlarging or changing the title if by so doing greater clearness is gained. It must be remembered always that the catalog is made not for librarians with technical knowledge, but for men whose use of it will be that of an untrained student. Let it be such that your constituency may use it without help. Be exceedingly generous with notes, never failing in the case of bills to show whether such bills became laws or failed in passage. If a bill became a law, give the citation. If reports or cases are known by special names, be sure to note that fact. Let there be no ambiguity either in title, subject or note. Annotations as to the substance of material are also highly desirable, particularly when they show whether a given article is favorable or antagonistic, or state the reliability of the author concerned. The material itself falls into three distinct classes which influence the cataloging treatment; books, pamphlets, and clippings. The books and pamphlets show comparatively little variation from regular cataloging methods. Clippings in the Wisconsin legislative reference department are mounted upon manila sheets, eight by ten, arranged chronologically under classification number, marked with a book number Z and treated as a single pamphlet. They have no author card, being entered merely under the subject-heading necessary, with the author line left blank. This procedure is convenient in some other cases, such as certain extracts from the Congressional record, containing discussions in which various members take part and where it is difficult to enter under any individual or even joint authors.
