How to get a bibtex-bibliography and a selfwritten “\bibliography” element together?

Question

I've got an external .bib file, which is written in bibtex and i can't add some elements into, because i just have the read permissions on it. When i build a bibliography element for my additional content, two indexes will be displayed..How can i tell Latex, that it should build the both indexes together?

Answer 1

Create another file, mybibliography.bib and call both:

\bibliography{theirbibliography,mybibliography}
