How about briefly clarifying where we stand with the elephant of copyright. I think the copyright act basically says photos before 1955 are all out of copyright and for films or artistic works its 70 years after the creator died or the date of publication for books.
It’s great on Trove when it’s out of copyright but various Australian galleries, universities and libraries seem to think differently. Some even consider they still have the copyright even if they have copied the newspaper article off Trove! It really bogs down your research when you have to keep seeking permission even if its already in the ‘Public domain’.
