Dear kiwidude,
thanks for your answer!

I see. Are you telling me that in the case of .djvu or .chm files it is better NOT to process them with your plugin in order to save time?

[kiwidude]

It is entirely up to you and the size of the books etc. You could always leave it running overnight if you have either a lot of books or some difficult ones to process. I don't use either of those formats myself to comment further on them.

Seems like an excellent plugin! However, I didnt find the option to extract the e-isbn in case it's present, instead of the regular isbn. Will it be implemented in the near future?

Hi,
I have just downloaded this plugin and I have a question.
I have selected 2000+ books. 22 Works have been created. PDF_TO_HTML crashed 3 or 4 times.

1) What happens in this scenario ? Extract ISBN continue after the offending books or the whole work (and the remaining search assigned to that work) stoppes ?

2) Also. Is there a way to resctrict the number of works to 1 ?

Select the one book and the run the plugin and it will just work on the selected book.

Yes, it would be good to get the eISBN instead of the pISBN.

That is better data, But...
How does using the e ISBN affect retrieving a cover that only exists on a p ISBN version of the book? Do you really want one of those (cheap) generic covers some Publishers are using?

For me, its not about the covers, so much, as finding the right edition when I add the book to my shelves on GoodReads. Having the correct eISBN can help immensely when a book has 50 other entries.

It's not about covers. It's about getting the correct ISBN number for the eBook. I don't use automated software to go find a cover. I do that myself.

[kiwidude]

I have no plans to add any support for different types of isbns and choosing one over another. The plugin looks for "digits" that might be an ISBN, rather than any sort of prefix due to the ridiculous number of variations possible. It would be a major change to make it do otherwise and it is not something I have enough interest in to do.

[Giuseppe Chillem]

Still no answer to my question:

What happen when a something like PDF2HTML crashes while extracting isbns ? Is the whole work of that particular job lost or does it continue ?

[kiwidude]

@Giuseppe - you had the error, so you should have seen what the result was based on whether it extracted isbns for other books in the batch or not. Of the top of my head I can't remember what the code would do, and having that PDF component crash is not something I see in my own usage to replicate (but then I try to avoid keeping PDFs where possible).

At a guess from memory this plugin breaks the work up into batches of some default size (50?). Each batch will get treated independently from each other, so an error in one batch should not affect others. As for what happens within a batch, my guess would be that with it being an unmanaged exception thrown by pdftohtml you will not get any isbn values from that batch back.
