Thank you all for the useful responses! I was particularly interested in the statistic "25% of the libraries sampled give workshops on how to use Wikipedia" from the Primary Research Group study.
I'm also getting more curious about how/if there is a need to serve the librarians beyond teaching them editing skills. I need to add this disclaimer: I'm an employee of the National Archives and Records Administration, and this interest/project does not in any way represent NARA policy or procedure.
Cheers,
