iDigBio - Integrated Digitized Biocollections

Annual conference on digital biological collections with free registration. It will be preceded by a series of short workshops September 15-17 dealing with natural history collections in the age of COVID-19, with the main conference happening on the afternoons (Eastern US time) on September 22-25. There are some superb sessions here. It's unclear from the web page whether the sessions will be recorded for later asynchronous viewing.
