Henry Holt and Company under the editorship of Professor C. H. Haskins,
by The Century Company under Professor G. L. Burr, by Ginn and Company
under Professor J. H. Robinson, and by Houghton Mifflin Company under
Professor J. T. Shotwell: such of these volumes as have appeared are
noted in the appropriate chapter bibliographies following. The
Macmillan Company has published _Periods of European History,_ 8 vols.
(1893-1901), under the editorship of Arthur Hassall, of which the last
five volumes treat of political Europe from 1494 to 1899; and a more
elementary political series, _Six Ages of European History_, 6 vols.
(1910), under the editorship of A. H. Johnson, of which the last three
volumes cover the years from 1453 to 1878. Much additional information
is obtainable from such popular series as _Story of the Nations_ (1886
_sqq._), _Heroes of the Nations_ (1890 _sqq._), and _Home University
Library,_ though the volumes in such series are of very unequal merit.
Convenient chronological summaries are: G. P. and G. H. Putnam,
_Tabular Views of Universal History_ (1914); Carl Ploetz, _Manual of
Universal History_, trans. and enlarged by W. H. Tillinghast, new
edition (1915); _Haydn's Dictionary of Dates_, 25th ed. (1911); C. E.
Little, _Cyclopaedia of Classified Dates_ (1900); _Cambridge Modern
History_, Vol. XIII (1911). The best atlas--a vitally necessary adjunct
of historical study--is either that of W. R. Shepherd, _Historical
Atlas_ (1911), or that of Ramsay Muir, _Hammond's New Historical Atlas
for Students_, 2d ed. (1915); a smaller historical atlas is that of E.
W. Dow (1907), and longer ones are _Cambridge Modern History_, Vol. XIV
(1912) and, in German, Putzger, _Historischer Schulatlas_. Elaborate
treatises on historical geography: Elisee Reclus, _The Universal
Geography_, trans. and ed. by E. G. Ravenstein, 19 vols.; _Nouveau
Dictionnaire de Geographie Universelle_, by Vivien de Saint-Martin and
Louis Rousselet, 10 vols. See also H. B. George, _The Relations of
Geography and History_ (1910) and Ellen C. Semple, _The Influence of
