I am so excited to see that the Colorado State Library is expanding their training website! I utilized some of their modules in a library customer service training I did. They are apparently going to be including Makerspace programming, potential funding opportunities, and resources.
The Tampa Bay Library Consortium also has a great website, Florida Library Webinars, with tons of free webinars. Anyone can view the archived content, but only Florida librarians are able to attend live webinars.
Keep on learning!
