Query: Excellent resource for Library Media Center specialists

This book gives an overview of the many types of reference materials, easily organized into chapters such as Indexes, Encyclopedias, Bibliographies, etc. Not designed for pleasure reading but more of a resource to guide selection in individual areas of references. Many resources are listed by name and described in detail. The amount of information included is comprehensive and can be a bit over-whelming at times. I would recommend this for Library Science students or professionals wishing to know more about reference materials or wishing to enhance their library's reference collection. The detailed bibliography at the end of each chapter provides supplementary resources for each topic.
