My library is slowly adopting web 2.0 tools. We've done a bit up so far, but now we've finally started a flickr account.
We always take pictures at our many programs, but then those photos just end up sitting on our staff network. They usually don't even make it our website. This seemed to me a sad waste, so I've been talking up using flickr as a storage and sharing tool for the last few months.
People were pretty tepid to the entire idea, and couldn't see why I cared. So, as a micro-project, I started using flickr just for some historic photos from our archive (and then integrated them into the website). Once people saw how flickr worked, and how it could be used, then they started thinking about what ways they could use it, too.
The first to dive in was our Children's Room librarians. The Children's Room is being repainted with a mural, and they saw that flickr would be a great way to share the progression of the painting - and by using a flickr "badge", they could also put these pictures right on a Children's Room webpage.
The biggest sticking point now is concern that patrons will be outraged if we post their photograph on the internet without first getting their permission. And this is legitimate, because although photos taken in public places are fair game, I wouldn't want to rely on a legal technicality. But I also think that it's not that big a deal - once people get used to it, there should be no problem (I hope).
So it's still slow going (slower than I'd like, anyway), but I am getting people on board. Perhaps soon we'll even find the $25/year to pay for a pro account, and really invest in this as a permanent tool.
