It is the fifth supplement to NBS Special Publication 457, Building Technology Publications 1965-1975, and lists CBT documents issued or recorded during the period January 1 to December 31, 1980. It includes titles and abstracts of each NBS publication and each paper published in non-NBS media, key word and author indexes, and general information and instructions on how to order CBT publications. This report communicates the results of CBT research to various technical audiences, as well as to the general public. Publications constitute a major end product to CBT's efforts and, in 1980, appeared in several NBS publication series (Building Science Series, Technical Notes, Special Publications, NBS Interagency Reports, and Grant/ Contract Reports) as well in non-NBS media such as technical and trade publications. Publications appearing in non-NBS media have each been assigned a five-digit number. NBS publication series abbrevia- tions are: BSS - Building Science Series TN - Technical Note SP - Special Publication NBSIR - National Bureau of Standards Interagency Report OCR - Grant/ Contract Report This document is divided into three main sections. The first. Titles and Abstracts, provides the report title, author(s), date of publication, selected key words, and an abstract of each NBS publication and each paper published in an outside source. The Author Index cites each CBT author and gives the publication title and/ or number referencing documents listed in this supple- ment. The Key Word Index is a subject index, listing word summaries of the building research topics for each publication and paper. By selecting a main word or subject, which are listed alphabetically, the user is able to locate reports of interest through the subject-related words found in the key word index. CBT is part of the National Engineering Laboratory, National Bureau of Standards. NBS undertakes basic and applied re- search in various areas. Interested readers will find other NBS publications listed in NBS Special Publication 305-12, Publications of the National Bureau of Standards 1980, from which parts of this report have been taken. Obtaining Publications Most current CBT publications (excluding NBS Interagency Reports and Grant / Contract Reports) are available from the Superintendent of Documents, U.S. Government Printing Office, Washington, DC 20402. Microfiche and paper copies of most CBT publications may be ordered through the National Technical Information Service, U.S. Department of Commerce, Springfield, VA 22161. Two other sources are depository libraries (libraries designated to receive government publica- tions) and Department of Commerce District Offices. The current price list and availability of publications listed in this report are given in Appendix C. The depository libraries listed in Appendix A receive selected publication series of the National Bureau of Standards for general reference use. While every Government publication cannot be sent to all depository libraries, certain designated Regional libraries are required to receive and retain one copy of all Government publications made available either in printed or microfiche form. To obtain information on which publica- tions are available, please contact the depository library in your area. Department of Commerce District Offices are maintained in the cities listed in Appendix B. Their purpose is to provide ready access at the local level to publications, statistical statements, and surveys. Each District Office serves as an official sales agent of the Superintendent of Documents, U.S. Government Printing Office. These offices make available for local purchase a wide range of Government publications. The reference library maintained by each District Office contains many Government and private publications, periodicals, directories, reports, and other reference materials. iv Contents TITLES AND ABSTRACTS Building Science Series 2 Technical Notes 4 Handbooks 6 Special Publications 7 NBS Interagency Reports 15 Grant/ Contract Reports 24 Papers Published in Non-NBS Media 26 AUIHOK irMLllLX KEY WORD INDEX 43 APPENDIX A Depository Libraries in the United States 68 APPENDIX B District Offices of the U.S. Department of Commerce 82 APPENDIX C CBT Publication Order Numbers and Price List 84 m Titles and Abstracts Old Absi^[ra©i^ 1 Building Science Series Building Science Series reports disseminate technical informa- effects of wane (deficiency in cross-sectional area) and decay, tion developed at the Bureau on building materials, components, which are additional problems.
