I have just finished The Librarian’s Nitty-Gritty Guide to Social Media by Laura Solomon. This is an excellent book on social media. Some aspects were familiar to me, but some were new. The concept of social capital, where marketing messages are seen as withdrawals of it (i.e. negative) was new to me, and makes me think about our twitter feed @GEHLibrary in a new light. Measuring return on investment was also something that challenged me. It was from an American public library perspective, but the principles will be very useful. I was also encouraged by the tips on how to keep going in the long term.
