Can I have two different styles of bibliography in the same document?

Question

It is possible in the same document, change the style of bibliography? I want the bibliography by chapters arranged in order of appearance. (I use unsrt), but I want the general bibliography in alphabetical order (and, if possible, backref to pages where the citation appears).

Answer 1

that's not really possible. What you can do is to create one bibliography, rename the file <file>.bbl to <file>-bib.tex and then run your document with the setting for the other bibliography. The first created can simply be inserted into your main TeX document by \input{<file>-bib}
