:before 1911 - 42 years from the publication of the work or the life of the author + 7 years (whatever was longer).
:from 1911 onwards - Life of the author + 70 years
It is our assumption that books published prior to 1911 are most probably out of copyright and hence we can use their artwork here in the compendium. A list of these books that we have used as sources of images can be found in the Subcategories list below.<br>
