According to Alison Flood on guardian.co.uk "Libraries throughout the UK are testing the waters of Twitter as a way to both engage with their readers and dispel their image as fusty, silent enclaves staffed by old-fashioned introverts". [No doubt this article was written by a journalist in a short break between a long liquid lunch and a boozy night out in a Fleet Street public house.]
The article points out that librarians are using Twitter to network among themselves as well as communicate with potential users. As Stephanie Taylor points out (my last blog) there are barriers to librarians using Twitter etc at work. Also it is very difficult to build up a following among your target audience. The recently launched Sheffield Libraries tweet so far has only 23 followers and many of those are organisations like SINTO rather than members of the public.
However, barriers can be overcome and followers will grow in number. My message to anyone thinking of sticking a toe in is "Come on in - the water's lovely!"
