Over the past year, David Procházka served on the planning committee for the 2020 OLAC Conference (http://www.olacinc.org/2020conference/). It was originally set to be held in Columbus, but had to switch to online delivery, due to COVID. The conference was held October 13-16, and David moderated half-a-dozen sessions by introducing the speakers, managing scores of questions, and keeping events on schedule. OLAC is a professional organization for catalogers, which supports the development of expertise in cataloging resources in many formats, including video, audio, and three-dimensional objects, by offering format-specific training.
Impressive work, David!
