  Abstract: In this study, I analyze the DBLP bibliographic database to study role of single author publications in the computer science literature between 1940 and 2019. I examine the demographics and reception by computing the population fraction, citation statistics, and PageRank scores of single author publications over the years. Both the population fraction and reception have been continuously declining since the 1940s. The overall decaying trend of single author publications is qualitatively consistent with those observed in other scientific disciplines, though the diminution is taking place several decades later than those in the natural sciences. Additionally, I analyze the scope and volume of single author publications, using page length and reference count as first-order approximations of the scope of publications. Although both metrics on average show positive correlations with citation count, single author papers show no significant difference in page or reference counts compared to the rest of the publications, suggesting that there exist other factors that impact the citations of single author publications.
