Hi @misbell I have a bunch of thoughts on librarians and professional development in OER/open pedagogy. I think it depends for me on where the librarians are in their development/interest in open. The Open Textbook Network (OTN), Scholarly Publishing and Academic Resources Coalition (SPARC), Creative Commons (CC), and Library Juice Academy (LJA) offer courses and certificates in open education. ACRL also has a road show that was being developed on OER.
I also think it depends on what your goal is for them on how they will support open projects. I think talking to them about their comfort and these goals could help too. I’ve worked with librarians that take a long time feeling comfortable with supporting these projects and others who attend a conference and dive right in. I’ve found the Open Ed conferences really helpful in my development and thinking around open. There’s also webinars through CCCOER and SPARC monthly LibOER calls and listservs.
I’ve participated in the CC certification and done the OTN train the trainer and can talk more about them offline. I know a fair bit one SPARC too. They each have their own goals and angle. I don’t know of as many open pedagogy trainings and have seen that more in webinars and journals, but I’m happy to chat and brainstorm this more. Oh this is also a bit older at this point (2018) but very useful - OER: A Field Guide for Academic Librarians - Open Textbook Library
