Mass proposal to core

Hi,

I’m not sure where it was the best to publish the post but I have a question.
I’m currently cleaning my collection to make sure all my books have the same type of title, that the authors are good etc…
As I have about 11.000 books and I wasn’t really meticulous it’s taking a bit of time.

The major part of my collection are manga (about 9.000) and mainly in french.
When I add the book I buy with the ISBN I often notice that a lot of books don’t have the number in the title (which can be tricky to recognize).

So two questions :

  1. Would you be interested that I push all the books once it’ll be done.
    My title formating is like that :
    City Hunter - TXX
    Then I can add some info if it’s a special cover, a deluxe edition…
  2. Is there a way to that in bulk ?

Another point is that I have some books with the same ISBN. There is two reasons for that :

  1. Sometimes french manga publishers are releasing a special/limited cover for the book. But they keep the same ISBN.
    Ex : Blue lock 15 has the standard cover

and the “Leclerc” one :

Another reason is that one french publisher is using the same ISBN for two books (bad bad publisher).

Ex : 9782374124292

How to handle that ?
