I want to use some of the contents from a public site in one my site pages. I would really appreciate if someone could guide me with a format if any (probably a few sentences that can be added at the bottom of the page). OR some other ways like mentioning in the beginning of the page. I think I should check with them directly as well.
In the archive’s terms of use: it says in 2 sentences where in one sentence it says not for commercial purposes. Will a website like mine (in signature) fall under this? And in other it says to mention their website name.
From the archive’s terms of use
-You agree to abide by all applicable laws and regulations, including intellectual property laws, in connection with your use of the Archive. In particular, you certify that your use of any part of the Archive’s Collections will be non-commercial and will be limited to no infringing or fair use under copyright law.
In addition, we request that, according to standard academic practice, if you use the Archive’s Collections for any research those results in an article, a book, or other publication, you list the Archive as a resource in your bibliography.
The two statements are not contradictory. The first states when you may use their material. The second states how you should use, if you may according to the first statement.
As far as the use you want to make of their material goes, explain them how and where you want to use it, and ask if that is permitted. The fact that your website is also meant to make money may or may not be decisive. Maybe it depends on how you want to use the material. But only they will be able to tell you.
I think you should check with the site. Tell them exactly how you propose to use their material, and check that they are happy with that.
I have two reasons for saying this. First, in the extract you quoted, there is no definition of “non commercial”. The fact that you had to ask if the term applies to a “website like mine” indicates that there is doubt as to its meaning.
Second, the extract you quoted doesn’t explicitly give you permission to re-publish the material. The first point says “your use of any part of the Archive’s Collections … will be limited to no infringing or fair use under copyright law”. That’s a badly constructed sentence, and it really needs clarifying.
