✦ Synopsis

A new edition of a standard work is always a welcome occurrence and this seventh edition of a directory of libraries in the Philadelphia area is no less so. The material contained in this directory will serve several uses. It gives in the alphabetical list the location of a particular library and hours when it is open. Further data are the conditions under which the library may be used and what facilities it has for making its material available by reproduction, photostat or microfilm.

However, the greatest value of the directory is for those seeking information on the subject resources of Philadelphia libraries. Each entry includes information on the major subjects covered in the library's collection and any special collections it may own. A subject index provides a ready key to this material. For example forty-three libraries are listed under the heading chemistry and others under chemical engineering, chemicals, chemistry-medical and pharmaceutical, and chemistry, physical. More specialized subjects such as catalysis, sugar, jet propulsion engines, linoleum might be mentioned as indicative of the range of technical interest of Philadelphia libraries.

A personnel index includes the names of the leading staff members of the libraries listed, in addition to serving as a membership list of the Special Libraries Council of Philadelphia and Vicinity.
