overs the mileage, the amount of railway capital, the earnings and

The Bureau of Labor issues three serials which ought to be found in
every library. The _Annual Reports_ contain the results of
investigations which the Bureau has made on industrial and social
subjects. The _Special Reports_ are on particular subjects, and are
prepared as requested by the President of the United States or by
either house of Congress. The _Bulletin_ is issued bi-monthly, and
contains the latest information on subjects within the wide field of
labor and not included in the other reports. The _Annual Reports_ and
_Bulletins_ up to 1898 are indexed in the _A. L. A. Index_, 2d ed. The
Bureau issued an _Index_ in 1902 which covers _Annual Reports_ 1-16,
_Bulletins_ 1-39 and _Special Reports_ 1-9. Application for these
publications are best made to the Bureau and handled from its mailing
list.

The most useful publication of the Library of Congress in a small
library is the series of bibliographies compiled in the Division of
Bibliography. They vary in size from approximately complete
bibliographies to small reading lists on questions of current interest.
Inasmuch as they are based on the largest collection of library
materials in the United States, the bibliographies give an idea of
existing references and sources which might not be suggested or even
known in smaller institutions. Through library loans and the judicious
writing for sources, the small library can supply liberal materials for
study from these bibliographies. As to the distribution of these
publications, the Library of Congress makes this statement: "With
certain exceptions, the publications are not distributed gratis, except
to institutions with which the library regularly exchanges." At any
event, they can be purchased from the Superintendent of Documents for
from ten to fifteen cents. The complete list of these bibliographies is
published in the _List of Publications Issued Since 1897_ (by the
Library of Congress).

The _Daily Consular and Trade Reports_ are issued from the Bureau of
Manufactures. These are a collection of reports made by United States
consuls in all parts of the world on matters of commercial and current
importance, such as new inventions, crops, market possibilities and
commercial relations in general. The Bureau will add a library to its
