Comparatively few of the works treating of the classification of North
American insects have been published as separate books; but such as have
been so published, if of comparatively recent date, can be obtained
through the regular book trade. By far the greater number of the
monographs and synopses mentioned in the preceding pages have been
published in scientific periodicals and in the proceedings or
transactions of scientific societies. These may be obtained either
through the societies or through the publishers; but single volumes of
transactions or proceedings, and more especially single papers, are
seldom sold, and the older volumes are liable to be out of print.
Moreover, the expense attending the purchase of all of the periodicals
containing the publications on a given order of insects will be so great
as to put them beyond the reach of most entomologists. The custom of
placing at the disposal of authors a number of separate copies of their
papers overcomes this difficulty to some extent and creates a small
supply. Thus it often happens that a person interested can obtain a copy
of a scientific paper by addressing the author personally. Many of
these separate copies also fall into the possession of dealers in
second-hand books, and may be purchased from them. The American
Entomological Society of Philadelphia, and also a few other societies
here and in Europe, offer for sale from their duplicates many of these
authors' extras, and in some cases publish lists. There are, moreover,
certain business establishments which make a specialty of the sale of
works and pamphlets on natural history, including entomology, and it is
chiefly through such establishments that the student is enabled to
secure the larger portion of the works needed.
By subscribing to the entomological periodicals published in this
country (a matter of but slight expense) the student may keep abreast of
the current literature. Short book reviews or notes published therein
call attention to the more important publications in other countries.
Moreover, the Zoologischer Anzeiger, edited by Prof. J. Victor Carus, in
Leipzig, Germany, and published every fortnight, gives a tolerably
complete bibliography of the current entomological literature at
intervals of about six or eight weeks. The "Naturae Novitates," published
every fortnight by R. Friedlaender & Sohn, Carlstrasse, 11, Berlin,
Germany, gives the titles of most recent works and pamphlets.
There are also three great annual publications, viz: "Die Fortschritte
auf dem Gebiet der Entomologie," published in Wiegmann's "Archiv fuer
Naturgeschichte;" "The Zoological Record," published by the Zoological
Record Society, in London, England; and the "Zoologische
Jahresberichte," published by the Zoological Station at Naples, Italy,
which give the full literature of the previous year, discussing the more
important papers and giving a list of the new species, besides other
information. These three publications are almost indispensable to the
student in any branch of zoology, and some one of them at least ought to
be found in every public library in the country. The volumes of the
"Zoologische Jahresberichte" since 1887 contain no titles upon
systematic and classificatory zoology, but only such as refer to
biology.
A not inconsiderable portion of the North American literature on the
classification of insects has been published by the Government of the
United States through various channels, foremost among which are the
Smithsonian Institution, the U. S. Department of Agriculture, the U. S.
National Museum, the U. S. Geological and Geographical Survey, and the
various surveys of the Territories. Some of these publications are
distributed free of cost; while others, like certain of the publications
of the Smithsonian Institution and the Geological Survey, are sold at a
moderate price to cover the cost of publication. Many of them are out of
print, and can only be obtained through natural history book-dealers.
Of the more general works, some may be obtained direct from the
publishers, and in such cases the publishers are mentioned in the
general list. The older works are mostly out of print and can only be
obtained from second-hand dealers. The current State reports of Lintner
and Forbes may be obtained from the secretaries of the respective State
agricultural societies at Albany, N. Y., and Springfield, Ill., while
the bulletins and reports of the entomologists of the various State
experiment stations, of which a large number are being published, may be
obtained from the directors of the respective stations. The older
reports of the State entomologist of Missouri and the State
entomologists of Illinois (Walsh, Le Baron, and Thomas) are all out of
print and can only be obtained by purchase from second-hand dealers. The
same may be said of the well-known and oft-quoted reports of Dr. Fitch,
which were published with the old volumes of the Transactions of the New
York State Agricultural Society.
