I'm writing a literature study in LaTeX. There are some studies I excluded from the search results. I would like to create a second bibliography with items I excluded. Right now, I've got this:

```
\bibliography{./bib/references.bib}

```

I would like to have a section/chapter before called "Unreferenced articles", with a few articles I did not refer to. Worth mentioning is that these articles are listed in `./bib/references.bib` but if I refer to them, they will pop up in the normal bibliography as well, which is not what I want.

I know about `\nocite`, but that's not useful in this scenario. However, if something like this existed, that would be great:

```
\nocite[unreferenced]{66, 142, 143}

```

to have articles 66, 142 and 143 pop up only in the *Unrefernced Articles* section and not show up in *Bibliography*.
