DBLP is an online database of academic publications in computer science and related fields. Handily, it provides a Java API for accessing the data programmatically. In this blog post, I share a few fun facts I discovered while using this API to explore the data that DBLP holds about two of the main conferences on programming languages; namely, POPL and PLDI.

The code I wrote to generate the numbers is available on GitHub.

*NB: A “paper” is anything listed in the conference’s proceedings on DBLP. This includes keynote presentations, short papers, posters, editorships, and regular papers.*

*Edit [27-Sep-2017]: I fixed a bug in my calculations for ‘most papers per conference’, which had led to some authors being missed.*
