When using the Import by ID feature using ISBN, the first search engine is ebook(dot)de, as explained in the jabref documentation. It seems that ebook(dot)de only provides one author in the author field (this has happened multiple times, I don’t know if it’s a general feature of ebook(dot)de). For example, for ISBN 0521099064, the [ebook.de output](https://www.ebook.de/de/product/3238810/stephen_hawking_the_large_scale_structure_of_space_time.html) shows Stephen Hawking as author, while the [ottobib.com output](https://www.ottobib.com/works-cited/e61a41660b) correctly shows S. Hawking and G. Ellis as authors. Shouldn’t the first search tool provide the most complete information?

I think it makes sense to switch the order. Ottobib apparently uses WorldCat as source

Do we need to open an issue at github, or will you do it Christoph?

Please open an issue, e.g. Change order of ISBN Fetchers.  
with the hint that ottobib uses worldcat  
Can be marked as good first issue,

This ISBN is not found at [ebook.de](http://ebook.de) at all: [eBook.de: eBooks, Reader, Bücher & Hörbücher online kaufen](https://www.ebook.de/de/search/no-results?q=9780203854693)

Regarding the book by Stephen Hawking, the database of [ebook.de](http://ebook.de) itself misses the author:

 ![grafik](https://canada1.discourse-cdn.com/flex030/uploads/jabref/original/2X/3/3c49b25e793fb34af21787b94dd1336e16d80dff.png)

Thus, we need an ISBN number, where the dataset on the homepage of [ebook.de](http://ebook.de) is correct, but the result wrong.

I tried with another book with two authors: [eBook.de: eBooks, Reader, Bücher & Hörbücher online kaufen](https://www.ebook.de/de/tools/isbn2bibtex?isbn=9783110702125)

It seems that [ebook.de](http://ebook.de) changed their return values and do not offer BibTeX name format any more. I asked them whether they can fix that.
