Do kids' lit bloggers influence publishing decisions? Are library systems basing their purchasing decisions on our recommendations? Should they? And to what extent is a blog about literature for youth a reliable source of information?
My short answers to the first three are not a lot, ditto, and no. As to reliability: while I don't see a lot of misinformation on children's lit blogs and am in fact impressed by the care which with bloggers source their facts, we first need to ask what we mean by information--and it's the answer to this question that tells us why blogs are not, generally, as useful to librarians as Betsy's first three questions would have them be. The glory and the bane of book blogging is its variety. Glory because lots of talented people are saying lots of different things about different topics in different ways to different audiences. Bane because this same riotous abandon confounds any but the most limited usefulness. While an individual can pick up the odd book-buying tip from reading the blogs, a library can't--it needs more systematic information than the blogosphere provides. A library collection based upon blog recommendations would be a mess.
If somebody needs a master's thesis, I wish he or she would take a look at whether or not there is such a thing as a blog-friendly book. We've had lots of discussions about bloggers all pushing the same books at the same time (a phenomenon exacerbated by blog tours) but I wonder if this is less a result of publishers pushing certain titles than it is that some books more than others will appeal to people who like to blog about children's books. Many bloggers are emphatic about their desire to write about books they personally love (and again, if a youth services librarian built a collection on the basis of what he or she loved, the library would be useless to the actual kids allegedly being served). There's a whole sub-genre of children's literature that has found its best audience among the adults who serve children (The Wednesday Wars, for example); does the same thing go on among bloggers?
