I've recently learned about two online library marketing courses that are starting on Monday, February 2. Here's basic info on both:
Feb. 1 – Feb. 28, 2015
$250 (Simmons GSLIS Alumni Price $200)
What you earn: Continuing education credit
"Marketing in the 21st century library is a four-week course designed for MLS candidates, graduates, librarians and paraprofessionals who are charged with creating marketing and promotions plans."
Feb. 2 – March 22, 2015
What you earn: an edX "Honor Code Certificate"
"Become a powerful advocate for the values and future of libraries and librarianship. Be informed, strategic, passionate, and unshushed!"
Personally, I signed up for "Unshushed" because I can audit it (not-for-credit), and because I've been curious to see just how a "MOOC" (massive open online course) works. Both look really good, and I encourage you to sign up for one of them -- ASAP!
