This document analyzes the co-authorship network of authors who have published in the VLDB conference over time. It finds that like other academic networks, the VLDB network exhibits the properties of densification over time, increasing clustering, and the presence of highly connected hubs. Key metrics like diameter and average path length remain small even as the network grows significantly in size.
