The Handbook for 1944 is the 36th issue. The times of moonrise and moonset, first printed for 1942, now include latitudes 40, 45, 50 and 52 degrees. Added this year are: (1) Table of precession for 50 years, to bring 1900-catalogue positions forward to 1950; (2) Table of representative bright variable stars, with maps of the fields of four naked-eye variables.
The Observer's Handbook for 1919. Edited by C.A. Chant.
Eleventh year of publication.
Note: pages 1-2 and 31-32 were duplicated in the printed copy.
The Handbook for 1919 contains the same amount of matter as that for 1918, and is thus of rather less than half its usual size. The reduction was accomplished by omitting those portions which are not much altered from year to year, namely:—
The Handbook for 1949 is the 41st issue. During the past decade its circulation has increased from 1500 to 5500. This year, for the second time, some advertisements of astronomical accessories are inserted. The Officers of the Society appreciate this assistance at the present time of financial difficulty. With regret the price has been raised to 40 cents.
The Handbook for 1948 is the 40th issue. During the past decade the circulation of the Handbook has increased from about 1500 to 5500. This year for the first time a number of advertisements have been included, calling the attention of readers to various astronomical accessories. The Officers of the Society greatly appreciate the support which the firms thus represented have rendered to us at this time of financial difficulty.
The first edition (1907) of the The Canadian Astronomical Handbook (later named the Observer's Handbook). This digital edition contains special introductory text written by former Handbook editor Roy Bishop in 2009.
