I have been writing about Flickr this weekend for my new book from Facet on Copyright and E-learning and I just had to say the more I use Flickr the more I really love it. For example, when looking today at the Library of Congress‘s photostream I came across these wonderful old photographs of different parts of Wales. There are a set of old photos of Aberystwith (sic). I particularly recommend Flickr for finding creative commons licensed photographs, although I was pleased to see you can now do a Google Image search for creative commons images as well (about time too!). You do need to do an advanced search though and personally I don’t find many people getting beyond the simple search. But by modifying the usage rights you can find images you are free to use.
