Not that I have anything particularly insightful to say about it, but flickr.com has become a very powerful research tool for this librarian. Sometimes you just don’t know what you are looking for until you see it. Lately I’ve been researching sustainable/green technologies for homes, and being able to browse through millions of images to gather information is really helpful.
I’m also blown away by the diversity and niche-ish-ness available from the various groups on flickr. For example, today I happened upon this group devoted to pens. Yes – pens. Good pens. Some really nice photography from the pen freaks. Makes me want to go buy a new pen.
