Among all the sites on the web that "foster the qualities of 'innovation, creativity, active participation, and collaboration'" (according to AASL through SLJ) are a few of those that I've recently been prodding. Certainly most of the sites listed are more traditionally educational that Facebook, Google Reader and Twitter, but I appreciate the recognition of alternative learning resources. GReader and Twitter in particular are great for finding and following interesting feeds (and twits, as I like to call them. "tweeting" is just so... cute?). Clicking through links and finding more and more information can be very addictive, as demonstrated by the massive number of tabs I have open continuously.
Also on the subject of internets and social sites, apparently tagging is becoming important as a reader advisory (RA) practice. Being kind of new to this, I don't know much about RA in general, but I'd bet it's a lot about knowing your collection (and beyond) and being able to help patrons (or whoever) find things that are good for them. Apart from *actually* knowing every book you've got, there are always jacket blurbs and being familiar with an author, if not the book specifically, to help with advising on a reading choice. That said, if tagging were to be used on books, it would be.. why, it would be like the subject index in the card catalog. No? Nevertheless, imagine having a tag cloud for your library, like mine, here and having everyone find books they might like through it.
And also in the world of reference and internet and research, credo reference is gathering reference engines and working with IP adresses to make getting access easier. Haven't had a chance to look into it yet, but definitely something to keep in mind.
In my absence from the public library scene, it appears that a new genre has developed. Mostly blamed on the massive trend towards porphyria in fiction, urban fantasy also covers other elements of fantasy in a gritty, reality-based settting. Presumably, this brings the traditional fantasy world closer to home, elevating the believability factor and perhaps making it easy to approach for readers today.
Here's a list of books about, well, books, from Library Journal. I can't say a lot about it because I haven't read them yet, but several will certainly make it to my (epically long) "read right after I've read all these other books" list. Someday, someday.
