I've gotten into the habit of creating snapshots of webpages via archive.org when pulling data from the web. It's successful 9 out of 10 times; sometimes a robot.txt file prevents capture or the Wayback Machine times out.
One such example from n78085212:
- 670 note:
Laois Education Centre (online), viewed September 19, 2015: $b Thomas McCarthy (born in Waterford [County in Ireland]; lived in Cork many years; works as a librarian; published several books of poetry, a novel, and personal memoirs; was a student at University College Cork) $u http://www.laoisedcentre.ie/LENGLISH/engrwww/tom.html
- Wayback Machine capture (Sept 19, 2015):
https://web.archive.org/web/20150919214431/http://www.laoisedcentre.ie/LENGLISH/engrwww/tom.html
That said, I don't bother with this for databases and similar sites, such as IMDb, VIAF, or an online newspaper or catalog.
