Tip: Make copies of photos that you want to put up on Flickr and put them in a folder on your PC. In the folder, you can name and organise your photos with different sets in different sub-folders. Then you can logon to Flickr, upload your photos and they are ready to show. I didn't do that on my first go and I found the Flickr organiser very hard to use. Now all I have to do is add some tags.
I had a look at Sutton Library's Flickr page and was impressed with the "New Books" photos that incorporate links to their catalogue.
There are some very interesting "Groups" around the subject of books, eg. book sniffers???
I finally got a photo of my own up on this blog with a link to my Flickr page.
