@mariaclaudia - I'm just about out of ideas

I downloaded La Exilada and La Promesa by Pearl Buck from epublibre.org, added La Exilada then entered her epublibre.org page into the Link field, it worked of course. I then added La Promesa and the link to epublibre.org still works See attached screen shots

You can see in the screen shots that it picked up the Publisher, Published Date and Tags from the inside the file, as well as the Author and Title.

Which operating system do you use - Apple OSX, Linux or Microsoft Windows? If Windows which 'edition' of calibre, 32 bit, 64 bit or Portable - I have tested 64 bit and Portable.

Aside : after the add, the Title Sort had 'La promesa' on pink, to 'fix' it I had to hit the button between Title and Title Sort which changed it to "promesa, La". The Author Sort field had "Buck, Pearl S." on green. I do not know if the book's language (Spanish) has any role to play in this, or the fact that it is different to the calibre interface language or my language setting in Windows. But I wouldn't think any of that has anything to do with the Author Link field - but maybe I'm wrong.

All Preferences with the exception of the L&F->Book Details->default author link template are the default settings.
