[R-sig-ME] Citing LME4 and Bates' Springer book (2010)

[rt]

What it the proper citation for the lme4 package and the Bates' book?
Also, can lme4 datasets (e.g., Pastes, ScotsSec, InstEval etc.) be
used for illustration in publications?  Can the authors grant
permission or is the permission from the source needed?

Many thanks for the package and the book.  When can I hold a
non-digital copy in my hands?

Thanks,

Russ
