From this history on Discogs:
user "belloga" added this credit link: https://www.bookogs.com/credit/590438-elisabeth-louise-vigee-le-brun
but this link "redirects" to this credit here:
John Butt (3)
Why is that?
I'm guessing the original Credit was found to be a duplicate and was retitled at some stage. Unlike on Discogs, users have the ability to retitle unwanted Credits.
The correct Bookogs Credit link is https://books.discogs.com/credit/362013-elisabeth-vigee-le-brun
Note: the ID "590438" is the same in both URLs.
Ah, OK. Didn't know that... what a surprise then!
We could at least make it a practice to provide the link in the entry's history: 'duplicate OF http://(credit)' — to make it a bit clearer.
Rather that just type 'df' or 'dfhgjdjtjh' something when reusing an entry: https://books.discogs.com/credit/590438-john-butt-3/history
