more current content? especially for training resources

Hello-

I am trying to get current content related to WCAG-preferably v2.1. Although marked (c) 2019, the W3/WAI website doesn't seem to have much info that is more recent than 2013, which is quite old in this context. The WAI handouts/flyer page (https://www.w3.org/WAI/flyer/#glance) is from 2009.

Is there a resource that has more up-to-date content? I want to learn more about accessibility myself, but I also want to share information with a national proposal team on this issue. Because the website doesn't really have downloadable content, finding handouts with key points that actually describe how to achieve accessibility in creating content would be extremely helpful. If you could direct me to current information-especially related to content authoring under 2.1-I'd greatly appreciate it.

Thank you,
Teresa
