How to cite Creative Commons works

A very useful guide is being compiled by Molly Kleinman in her Multi-Purpose Librarian blog. As someone who licenses a lot of work using CC-BY, and who both re-uses and sometimes re-mixes a lot of CC work (especially photographs) for both academic and creative ends, I recognise that it isn’t always clear exactly what “attribution” means, for example. Kleinman gives examples of ideal and realistic usage (the real name of a copyright-holder and/or title of a work may not always been known, say), and makes suggestions for good practice and compromises. This is a very welcome service, and I hope that more examples and comments follow.
