Wikis

I really liked the Mint Wiki from the Mint Museum, Nth Carolina. It clearly states what the wiki is for and has a lot of carefully selected info and links on each exhibition. It is one of the few wikis I have seen that is current e.g. it has information on upcoming exhibitions.
As for a wiki with library content, I like Possible Next Generation Catalogs. State Library of Tasmania's catalog is worth looking at. The catalog makes a suggestion if spelling is incorrect like Google and Amazons do and is really user friendly.
I couldn't work out how to access the Wisconsin Heritage wiki.
I think that wikis are great for the library to set up for book clubs - for posting reviews, putting up links to all things book-related, even showing members how to create their own wiki.

Smiley face moon

I found this photo on Flickr. I can remember being out on the verandah just looking up at the sky and discovering this for myself - I only became aware of media coverage on this event later on. I was quite excited and actually took a photo myself. This photo was taken in Brisbane on 1 December 2008 when Venus, Jupiter and the crescent moon looked for all the world like a smiley face. Check out Smiley face moon on Flickr along with other great photos of Brisbane by this photgrapher.
