As publishing inevitably involves crossovers these days (the film of the book of the tv series) I find this site (with newsletter) very interesting, and probably useful to library staff - as users often enquire about items precisely because of these crossovers (the same material may appear on our catalogues as book, comic, talking book, large print, DVD, etc)
People are also interested in authors (aside from their work) and interviews and so on...
A great online resource! Books & Media
For a specific example of the depth of the resource, look at their listings for this week's radio shows which include items of interest to book lovers (although note that after a free trial, someone would have to pay for a subscription to access the complete resources).
