Public libraries can include their technical service departments in public relations programs. There are four different approaches: (1) guided tours of the technical service departments, (2) exhibitions on the processing of books, (3) publications describing the technical services, and (4) publicizing the technical processes of the library in local mass communication media, such as the newspaper and radio station.
The automated printing techniques used to produce the seventh edition of the Library of Congress subject heading list and its supplements are described following a brief history of the printing of the first six editions of the list. Possible benefits accruing from the use of the new techniques are mentioned, and some of the problems yet to be solved are identified. Guidance in determining the date of publication of the eighth edition of the list and in establishing future patterns of frequency and cumulation for the supplements will be sought from users of the list.
Books are now categorized only as rare or non-rare; a "permanent research value" category is needed, as well as a binding standard based on non-destructive methods. Suggestions are made for less destructive binding; it will be more expensive, but will aid survival of the books. Several means of deacidifying deteriorating paper are under study. Non-archival lamination should be avoided for permanent materials. Criteria are listed for selection of a binder for rare books. Library schools seem to ignore book conservation; to avoid the eventual loss of virtually all books, a specialized profession is needed.
Growing library collections have focused attention upon the need for selective storage and weeding of the materials. Certain objective measures for determining which items in a collection may be retired to storage are presented, and an example of the use of such measures at Columbia University is described. It is concluded that the criteria for weeding and storage must be selected on the basis of the goals of the institution in question and of the various patterns of use in different disciplines.
The rules of the AACR for entering legislative enactments (constitutions, treaties, statutes, ordinances, rules of court) under conventional headings follow, with modifications, recommendations of the American Association of Law Libraries. These headings constitute a class of their own; individually, they should be viewed as integrated entities and not be explained in terms of their components, or as author headings with subheadings. Entries for court rules and the relationship between conventional ("category") headings and subject headings are also discussed.
