This question already has an answer here:
How can I create a link from a PDF-Reference to another external PDF? I want to reference a source and when you click on it, the document should jump to the bibliography like normal. An then i want to put all sources from the bibliography to a seperate folder as PDF-Files. Then when I click to a source itself in the bibliography I want that my PDF opens the book or what ever is referenced and the correct page with the marked text. Does somebody know if that is possible in latex in some way? Maybe with a kind of hyperlink to the PDF and some parameters to directly open the correct page? Thank you !
