Example

https://www.librarything.fr/work/28742967/book/223830118

Authors add, too

Sorry, OK after few moments

Problem with "date de naissance in . fr
it's ok in . com
https://www.librarything.fr/author/bersteinserge

Here 1934-10-18

xxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Or this !!!!!!!!!!!!!!!!!!!

https://www.librarything.fr/author/lebrunclaude for date of death 2019 and not 1919

Not only French LT.
I can't change the date of the Dutch translation of Michael Kohlhaas, that is wrongly set at 1960 instead of 1940. If I change it, it appears right at https://www.librarything.com/work/65731 (and then I removed it, see 'history'), but still wong at https://www.librarything.nl/work/65731

Just to remember.
