The SPA journal, originally titled The Monthly Register of the Leonard Observatory, was typewritten and not widely distributed. 68 In 1911, after publishing several technical articles in Popular Astronomy, Leonard advertised the SPA to the broader audience of Popular Astronomy readers and invited others to join.

The Astronomical Society of France established a Variable Star Commission in 1901. The Astronomical and Astrophysical Society of America, formed in 1897, heard 21 papers on the subject of variable stars in its first 13 years, but as yet, there was no organized group devoted to variable star work in the Americas.
