By 1959, Struve had published more than 900 journal articles and books, making him one of the most prolific astronomers (probably only Ernst Öpik published more, with 1,094 items). Many of those works aimed at popularizing astronomy. In particular, he published 39 articles (and 10 other items) in "Popular Astronomy" (1923–1951, the journal was discontinued in 1951), 154 in "Sky and Telescope" (1941–1963, the journal was started in 1941) and 83 reviews of books and works by other astronomers. Most of his co-authored scientific articles were co-authored with Pol Swings and were dedicated to spectroscopical studies of peculiar stars. To explain his interest in this topic, Struve once noted that he had never seen a spectrum of a star where he couldn't find anything to work on.
