BIBLIOGRAPHY OF LITERATURE ON SAMPLING.
(Compiled "by W.J. Sharwood and M.W. von Bernewitz)
So far as is known, tnere is no complete bibliography on sampling,
therefore, this one should be of value. In it are nearly eleven hundred refer
ences, some dating back 30 years, on sarrpling at mines, mills, smelters, power
plants, pumping stations and refineries. For convenience, there are included a
:ew references to methods for sampling such materials as leather beltinfc in mills,
salt impregnated soils, and mine waters. All the important technical journals, -
including some in foreign countries- and engineering society publications, also
mining and metallurgical text -books, have been studied for anything concerning
sampling, and while it is not claimed that every important reference has been
listed, the bibliography is fairly complete.
The arrangement is alphabetical by authors1 names, and the references
are numbered serially in the order that they appear in the bibliography. Anon
ymous references are listed under the name of the journal in which they appear,
and are numbered like the references bearing an author's name.
Patents are grouped in their numerical order, without index numbers.
Under the heading, "U.S. Bureau of Mines Publications", are listed all
publications of the bureau that deal with sampling. While the serial number is
omitted, these same references, of course, have serial numbers where they appear
in the list arranged alphabetically by authors.
Acknowledgement is made to Miss Florence Wilkie and to Miss H. Shelby
Holbrook, who assisted in revising the manuscript.
