The mineral deposits of South America, by Benjamin L. Miller and Joseph T. Singewald, Jr., published in 1919, was prompted by the interest in South American mineral deposits aroused during the World War. The present war has directed attention to the mineral deposits of South America to an even far greater extent.
Since 1919 so much more literature has been published concerning the mineral deposits of South America than prior to 1919, that The mineral deposits of South America no longer adequately presents existing knowledge of those deposits. Furthermore, the book has been out of print since the fall of 1942.
The present demand for information concerning the mineral deposits of South America is unprecedentedly great and widespread as well as urgent. The task of digesting the literature since 1919 and presenting it in a second edition is so great that the emergency demand for information would be over before a second edition could be made ready. Moreover, there is a tremendous amount of new work being done in South America that will not be available for publication until after the war. It is, therefore, an inopportune time to undertake a revision of the original edition. Such a revision should await the release of the results of the war work in this field.
With the purpose in mind of some day preparing a second edition of The mineral deposits of South America, the author has been supplementing the bibliographies in that book with the current literature . . .
