Upgrade StorageImport catalogue
Given:
In a book I own, the following ISBN is printed: 3-456-83964-2
Note: Additionally, as in every German book, the German National Library is listed: https://www.dnb.de/DE/Home/home_node.html
Process:
1. When I imported this to zotero, the catalogue was "BnF ISBN" and provided an ISBN of 978-3-456-83964-6.
2. I then imported this "new" ISBN (978-3-456-83964-6) again (for testing). The catalogue used this time was K10plus.
3. Checking their web site, I found that K10plus also provides data for the initial ISBN: https://k10plus.boss.bsz-bw.de/Record/(DE-627)1603446737
4. Checking their web site, I found that WorldCat also provides data: https://search.worldcat.org/de/title/248943003
Questions/Comments:
Why isn't WorldCat used? This should be the case, shouldn't it?
Why does the catalogue change at all? (Not that I like K10plus, but why does it change?)
Are there any plans for removing K10plus? This catalogue is used for multiple entries of mine. And in my opinion it is the worst ever. As far as I get it, it collects all data from every real world library and thereby has lots of duplicated books with all wrong information.

adamsmithBecause Worldcat has comparatively poor data, slow performance and will on occasion lock users out, it's the last catalog we query for ISBNs We query the catalog APIs (SRU, technically) sequentially with BnF before K10plus and BNF doesn't appear to return a hit for the ISBN-13, for whatever reason, so K10plus is queried next. Zotero converts all ISBNs to ISBN-13 on import because ISBN-10 are discontinued. No. K10plus doesn't query 'every real world library' but is the consortial catalog of large German libraries (specifically, the combined GBV and SWB consortia) and has, in our experience, excellent metadata. It also has a fast and reliably API for said metadata. What you describe sounds much more like Worldcat.

DWL-SDCATo further pile-on negatives about WorldCat: It is a "union catalog" that is the (not-very-merged) contents of tens of thousands of individual library catalogs. The quality of the data entry to each of these individual library catalogs varies from near perfection to preposterously careless. It is common to find many records from a single ISBN with different degrees of completeness and accuracy. It is common to have WorldCat records found by entering an ISSN that list several editions of a book (each of which have different true ISSNs, different publication years, different pagination, different numbers of chapters, etc.).
