Copyright and Copyduty

The Worldwide Web is a veritable treasure of information and illustrations. Of course, much of it is not original but copied from documents, reports, photographs, newspaper articles, and so on. Copyright is a controversial topic. It may be foregone in case of non-commercial use, or be satisfied by crediting the source. Older documents may be in the public domain.
Since one of the idealized purposes of the Web is to "replace" libraries and serve as the ultimate depository of all data, information and knowledge, many people consider it a private duty or mission to help making up the backlog. In several instances, this is an organized effort, involving unemployed volunteers. An example is the Gutenberg Project; its website provides much information on copyright. In my case, I pick my own materials.
An example is my "discovery" of a present my father received in 1975 in the form of a booklet entitled: "Oud-Amsterdam: 100 Stadsgezichten" (Old Amsterdam, 100 city views) by L.W.R. Wenckebach, issued by the Dutch "Daily News": "Het Nieuws van den Dag", in 1907. Checking on the internet, I noted that very few of these illustrations appear on the WWW. The paper itself was discontinued and taken over by the "NRC Handelsblad."
Search of the name Wenckebach revealed that the illustrator was also involved in the well-known VERKADE's alba. (see Marga Coesel: "Natuurlijk Verkade", Uitg. Terra, 1999), There also is an Attorney by that name on Information Technology Law, Telecom and Internet.
I selected 12 pages to scan and translate. (right), and added the colorful link below:
