I do the same, Herb. The individual clippings serve, if you will, as "live" advertising billboards; that's why Newspapers.com uses them. And that's a very valuable benefit for researchers.
I'm also, albeit slowly, trying to get into a habit that seems to be becoming more prevalent on Wikipedia. If an item used in a source citation may be difficult to locate elsewhere, e.g., a Newspapers.com clipping or a free-to-view Ancestry.com source image, I try to remember to hop over to the Internet Wayback Machine and get a capture of the URL, then post both links in the citation. There is nothing so diaphanous or impermanent as an internet link.
Not to reignite past copyright discussion on G2G (for that see an earlier discussion here last January)--and I'm speaking only of U.S. law here, being applicable to me as a U.S. citizen when I find a U.S. publication originally made prior to 1926 (or an applicable government publication) and that I then post on a U.S.-owned website--anything published through 1925 is in the public domain. U.S. case law, including Supreme Court decisions, has made it clear that two-dimensional items in the public domain that are subsequently copied or reproduced with the intent of replicating the original cannot themselves then be copyrighted. The new scan, image, or photograph remains in the public domain unless a new "creative layer" is added, e.g., by translation, revision, annotation, illustration, or other means that must then be part of the new item, not simply something extra accompanying it.
Newspapers.com and other sites have a lot of imaged material that was published prior to 1926, and if I find an interesting obituary or marriage announcement published before that, I save the item as a JPEG and will upload it to WikiTree if I believe it might be of use to others (the downloads can be very large, so I'll often also Photoshop them to a more web-friendly size). As of January 2022, items published in 1926 will enter the public domain.
The U.S. clarification was needed in part because Betsy's William Stitt was born in Kirkcudbrightshire, Scotland, and died in Montreal. In the small world department, ancestry in Kirkcudbrightshire is the farthest back we've been able to trace my yDNA line.
