Copyright
I first came across copyright connection to libraries in the MLIS when I audited the publishing module. This was interesting but very dry as it was full of legal history and jargon. The lecturer actually hated some of the copyright laws especially the lifetime of some copyright restrictions on works. The example they used was James Joyce whose grandson was still living off the proceeds. They were a publisher themselves
Caroline's great blog post condensed and updated a lot of the information on photos creators rights. As a librarian I am familiar with attributing correctly when quoting from articles or books but only lately has it sunk in that I should be just as rigorous when it came to photos.
Throughout my education I am not sure I accredited pictures I used for projects thinking that if they were on the internet or published I could just use them freely. For this course I have been very careful to use either getty royalty free images or pixabay images.
I have worked in an institution who had several large photographic collections of local historical interest. Using Creative Commons licensing would be a way of promoting themselves and still maintain ownership and ensure the safety of their collections.
