BibTeX, biblatex and biber ⇒ citing preprints?

[drowsy]

What is the proper way to enter preprints into the database
and cite them?

I certainly know the authors and titles,
but no year for sure.

And my current bibstyle is natbib/authordate1

I would either handle this according to the type of document (@booklet, @manual, @misc, @phdthesis, ...) and use a suitable field or just simply declare it as @unpublished in the BibTeX database (*.bib). Perhaps you can find more information (and inspiration) in the BibTeX manual.


Best regards

Declaring preprints unpublished does not really help.
What I get is [NAME, n.d], because the year is "not defined".

I am suprized, nobody ever cited preprints before?

Weird, now I put "year={preprint}", and it works!
I get "(AUTHOR, preprint)".
I remember it did not work before.
Maybe it was before I switched to natbib...
