I am no Lawyer. I use layman terms to understand Law, the following is my common sense understanding of applicable law and what WikiTree requires. (comments & critiques are always appreciated).
There seems to be a few different trains of thought on this subject.
IMHO Patricia, Dave and Martin all seem to be on track.
I have recently joined the euroartisto Project. Many previously normal Source's have run-out or simply do not go back before c.1325.
These two Profiles below I created and Manage are based upon online free google books that I have had to download the whole book to my PC to read any of the text. They are under no existing Copyrite protection. (you may notice I quoted verbatim from these Sources & also gave credit to the Source witch produces accuracy & allows for further study. I have also included the Re-Publication Sources).
Items: VI, VII, & VIII from the WikiTree Honor Code: http://www.wikitree.com/wiki/Special:Honor_Code
VI. We respect copyrights. We don't knowingly copy information that's owned by someone else. If we ourselves want to preserve a copyright, we're clear about what's copyrighted so others don't accidentally copy it.
VII. We give credit. Although most genealogy isn't copyrighted, researchers deserve credit for the work they've done.
VII. We cite sources. Without sources we can't objectively resolve conflicting information.

Here is a link to a WikiTree Free-Space page I made in Jan 2016.:

Here is a Photo Image example of a "NON-COPYRIGHT", "Rights Advisory: No known restrictions on publication" Image I have attached to a Profile (Always being sure to follow WikiTree guidelines / Honor Code).
