PUBLICATIONS

OF THE

BUREAU OF STANDARDS

[7th EDITION-FINAL]

Complete from establishment of Bureau (1901) to June 30, 1925

FOREWORD

In addition to the tests and comparisons made by the Bureau of Standards, its work includes such researches as are involved in the establishment and maintenance of the various standards and units of measurement, the development of measuring instruments and methods of measurement, the determination of physical constants, and the properties of materials. The results of these investigations are published in pamphlet form, and in the following pages is given a descriptive list of these papers. The papers are issued in eight separate series designated as follows: S=Scientific Papers; T = Technologic Papers; C = Circulars; H = Handbooks; R = Simplified Practice Recommendations; L = Limitation of Variety Recommendations; BH = Building and Housing, and M = Miscellaneous Publications. They cover a wide range of subjects in the field of physical measurements and the properties of materials, and are issued for general distribution to the scientific, technical, and industrial interests concerned with the subjects treated. Series S and T may be subscribed for in advance by volume, addressing the Superintendent of Documents.

The official distribution of a limited free edition includes single copies to the technical press, designated Government depository libraries, those collaborating with the bureau in its investigations, organizations exchanging like courtesies with the bureau, and certain specialists concerned with the subjects treated. Others, however, may purchase them from the Superintendent of Documents, Government Printing Office, Washington, D. C., at the prices stated. When applying to the Bureau of Standards for any of these publications, merely state the symbol and number preceding the title; when ordering from the Superintendent of Documents, give symbol and number of publication and name of bureau.

This general circular will be revised from time to time. A supplement to this circular brings the list up to date and contains a list of bureau publications not obtainable and which may be consulted at some designated Government depository library, and the publications that have been delivered since this circular was issued.

The supplement contains an index which, with the index to the main circular, affords a complete topical reference to the published work of the Bureau of Standards.

1. ANNOUNCEMENTS OF NEW PUBLICATIONS

In addition to Circular No. 24 and its supplement, the bureau
publishes announcement cards giving titles and prices of new
publications. These cards will be regularly sent to any interested
persons, upon request.

2. TECHNICAL NEWS BULLETIN

The TECHNICAL NEWS BULLETIN of the Bureau of Standards
was issued in mimeographed form and sent to a limited mailing list
from June, 1919, to April, 1925. It was then decided to publish
the BULLETIN in printed form in order to care for the increased
demand. The first number to appear in that form (Bulletin No.
97) was issued in May, 1925. The BULLETIN can be obtained on a
subscription basis from the Superintendent of Documents, Gov-
ernment Printing Office, Washington, D. C., at 25 cents per year.
It is issued once a month and contains short items describing
progress of work in the laboratories, notices of important meetings
which have taken place at the bureau, and a list of publications
released during the preceding month.

3. DISTRIBUTION

A small bureau edition is available for an initial official distri-
bution to libraries, technical journals, and experts who, cooperate
in the work or who are directly concerned with it. Others may
purchase the publications from the Superintendent of Docu-
ments as described below at the nominal prices shown.
