Thank you for the ALIA new graduates list for audience development officer, which was discussed in January as a new synonym for the word "librarian". It came from a posting by Stacey Bale aboutan article in the Daily Telegraph (UK) on 12 January. The rebranding attempt by the city of Edinburgh provoked a threat of industrial action from librarians, although they seemed to be more worried about an attempt to introduce self checkout machines.
The term got picked up by the Wordie site, which is an interesting and curious place ("like Flickr, but without the photos"). As well as listing half a million words, it provides links to many online dictionary, and its own image search. Do an image search on audience development officer, for example, and you will find a selection of pictures of audience development officers - none of them, alas, in libraries, which should set the minds of the librarians of Edinburgh at rest.
