BIBLIOGRAPHY
For obvious reasons this bibliography is not complete; to make an exhaustive catalogue of the titles dealing with the stone age in America would require the inclusion of many articles in out-of-the-way periodicals and newspapers that are now lost or out of print; in the next place, if made complete, even within the limits of possibility, such a list would require a separate volume out of all proportion to the dimensions of the present work.
In view of these facts, therefore, the attempt has been made, first, to give the publications to which reference has been made in the text; second, to present a list of general works of standard reputation, most of which are provided either with indexes or tables of contents raisonnés; third, to give some of the more important series of publications of individual authors dealing especially with excavations whose results are germane to the matter of the volumes; and fourth, to set forth a classified list of references by the use of which a student can at least learn something about the desired subject and at the same time may receive suggestions as to the methods and the literature necessary to further research.
In view of the change in archæological processes and opinions that has often occurred in a comparatively short space of time, the arrangement of the titles is made as a whole in chronological order.
