The appended reading matter is amply suggestive of the best practice, and illustrative of the errors to be avoided, and should be read with studious attention. Note the insistent emphasis on uniformity and consistency, attainment of which requires a definite adherence to a decision once taken; the choice of popular, rather than scientific or technical names; use of terms of permanent character; avoidance of foreign terms where there are English equivalents; choice of most specific subject; constant aim at ease of consultation, best obtained by placing oneself in the position of a reader; constant guard against the occurrence of synonymous headings and the useless multiplication of headings; care not to misuse national adjectives and geographical sub-divisions; inclusion of the necessary references, etc. Do not overlook the utility of a card list of the subject headings in use. The A.L.A. list of subject headings for a dictionary catalogue; Library of Congress list of subject headings; A.L.A. Catalogue, with supplements; Mann’s Subject headings for juvenile catalogues; Sears’s List of subject headings for small libraries; and good encyclopædias, are extremely useful guides and should be closely studied. Students should make a special point of reading those portions of the preface to the London Library Catalogue which deal with our subject, and examine the separately published Subject Index. The inclusion of form entries is often carried too far. Weigh carefully the value of such entries, and in examining catalogues give special consideration to the question as to whether the advantage of their inclusion is commensurate with the space required.
