Small update to v.6.0.2.: info added of co-author, if known

File "calibre_plugins.BOL_NL.worker", line 212, in parse_details
KeyError: 'author'

The interesting thing is that the book was actually retrieved, because sometimes the log contains information that isn't in my Calibre (series name and number).
Here are the logs for several books, all with the same error:


PS: There are apparently two different versions of single quotes. Can you correct that in your book search (is the same with the old version-so new request)?

Thanks for your testing. It is very usefull.
I presumed that, if the json dictionary was found, all info was in there.
I was wrong, p.e. the author is not always given, resulting in the key errors.
Not only authors, but also publisher, relase dates, isbn. Sometimes with a different key
So I added some other keys and after that, the plug-in will try the old ways of scraping for the missing item, if not found in the json-info
That's is little more complex.

I also implemented a way for the different single quotes ( yes there are different ones), but don't know if that works. I have no good example for testing.

So a new version 6.1.0 is now available.
Please lety me know if you encounter issues

[Dompie]

I've updated several books where the plugin version 6 wasn't working, and they all work. So, it seems to be working perfectly again for me.
I don't have an example of several single quotes at the moment because I always copied the correct title from the log and changed it accordingly. If I encounter another one, I'll let you know.
But for now, you've got it all working again, and I'm very satisfied.

[Dompie]

@Pr.BarnArt Single Quote: I have handled 5 different books with single quotes and all went perfect. So I think your implementation is correct.

[Dompie]

I have the log of a single-quote book that slipped through your special treatment. Attached is the log. It's certainly no problem to fix, but since you've created a special conversion and almost all single-quote files work fine these days, I thought it would be nice to share it with you.

Bol.com Bol.com seems (now?) a React/Remix app that serves its initial HTML with JSX-style self-closing tags. I won't bore you with the details, but that produces errors exploring the resultpages.
Made a fix for that with version 6.2.0, as usual also available at thet start of this thread.

Thank you for notifying, and the example you posted.

Can you try again, with the book you mentioned I got all metadata- no errors

[Dompie]

I think BOL has changed something again. For books of recent date (from March 2026?), there is no response if you do not enter an ISBN number. With an ISBN number, everything works as normal. There is no error message, absolutely nothing, just no result without an ISBN.

Logging of an example without and with an ISBN:
