Yesterday was Public Domain Day. Here is a list of some authors’ with works entering the public domain
http://publicdomainreview.org/2013/12/10/class-of-2014/ . Mostly these are countries with life + 70 years but it also covers some with life + 50 years like Canada. The shorter the extension, the better for everyone.
Not as much is happening in the US, which has a longer term.
