Does putting material on a course blog or website count as publishing?
For the purposes of copyright, uploading material online counts as publishing since you are making the work available to the public. As such, posting substantial amounts of a work online (e.g. a pdf of an entire article, a photograph, a video clip) requires permission from the copyright owner for this particular purpose. However, posting a link to the item, or a link to the library database through which the article can be accessed by licensed users, does not consitute publishing and is always an acceptable way to share information.
