Prevent figures/listings from being inserted into specific parts of a LaTeX document

I have a part A in a document with some text and listings/figures in between. The figures and listings are positioned using htb.

Following this part A, there is the bibliography. However a couple of figures do not fit and are therefore are offset to another page, which is fine. But: I do want to limit the offset space to part A and not have the figures be placed within the bibliography text. Also, I don't want to force page of float for all figures (hp positioning or something). A page of floats at the end of part A and before the bibliogra开发者_运维技巧phy would be fine.

So my questions is, is there a way to exclude some parts of a LaTex document from being used for positioning floats that did not fit someplace before?

Maybe I'm missing something, but couldn't you just put a \clearpage right before the bibliography? That forces out all floats that haven't found a place yet.
