independent bibliographies in one document

I am working on a document where each abstract has its own bibliography. How can I put references for each contribution independently of the others? I am currently using natbib, but if you guys have some better ideas, I'm all ears!

• Thanks. Although, here I would like to print the relevant bibliography without creating sections. Do you know any resource I can refer to? I checked the biblatex documentation, but it's somewhat obscure to me...! – RobertP. Jul 25 '16 at 12:44

In biblatex there is the possibility to use the refsection environment:
\begin{refsection}

With this \printbibliography will only print the items cited within this environment.
