In the UK, there is a a move toward including marketing materials with each book checked out from the library. In libraries in Essex, Somerset, Bromley, Leeds and Southend, up to 500,000 promotional flyers will be handed out to patrons. The solicitations will be placed on the inside cover where the due date can be found ensuring that the advertisement is looked at least once.
As is noted by one concerned observer, impartiality and free access could be impacted by the increasing power of marketers in these public sector arenas. Certainly one could see a conflict if a major advertiser demanded a book be pulled from the library shelves. If a library relies on that advertising dollars, how might it respond to book bans?
