### Separate bibliographies per chapter?

A separate bibliography for each 'chapter' of a document can be provided with the package chapterbib (which comes with a bunch of other good bibliographic things). The package allows you a different bibliography for each `\include`d file (i.e., despite the package's name, the availability of bibliographies is related to the component source files of the document rather than to the chapters that logically structure the document).

The package bibunits ties bibliographies to logical units within the document: the package will deal with chapters and sections (as defined by LaTeX itself) and also defines a `bibunit` environment so that users can select their own structuring.

`bibunits.sty`
