The description on the NARA Virtual Genealogy Fair says:
"On October 26 & 27, 2016 (Wednesday & Thursday), the National Archives is hosting a two-day, virtual Genealogy Fair via webcast. Viewers have the opportunity to participate with the presenters and other family historians during the live event on YouTube. All of the session videos and handouts will be available from this web page free of charge. You can watch the sessions and download the materials at your convenience. Registration is not required."
The list of times, speakers and topics is at https://www.archives.gov/calendar/genealogy-fair. Note that this is 10 a.m. Eastern time until 3 p.m. Eastern time. Please do your own time estimate so you don't miss anything.

It is not clear to me where the session handouts will be available. Perhaps they will be on the Genealogy Fair webpage (https://www.archives.gov/calendar/genealogy-fair) after the broadcasts.
