Invalid ISBN prohibits saving a reference

Discussion

I find it surprising that an invalid ISBN means you can’t save the citation. The flag that it ISBN is invalid is very helpful! Curious where I should stash the invalid ISBN for reference later (as it was listed by the original reference). Something like a notes, or for invalid versions to not prohibit saving a book reference.

Here is the reference I was trying to save as a book: https://www.researchgate.net/publication/368778168_Mammals_of_Rancho_El_Aribabi_in_the_Sky_Island_Region_of_Northern_Sonora_Mexico

With the invalid ISBN “979-8-218-15237-6”

If you add an ISBN to the ISBN field when creating a new reference or editing an existing reference, our backend can check if is valid, so that is why we don’t allow the creation of a reference with an invalid ISBN, @anna. If you wish, you can add it as a note by clicking the notes button (speech bubble) under the reference in your library.
