Where to find documents/information about research group policies Due to different problems I have had in my research group (I am the PI) and in order to solve them I have decided to write down in a public document, what is our research group policy.

I considered did useless before since I considered it to contain laws that are straightforward in most of the cases, but now I realize about its importance, with the hope that previous problematic situations will not happen again.

The document will contain directives about who and how will lead research projects, what can be expected from the PI and the members, authorship and participation in papers and patents, who can add new members, how will be new collaborations established, etc.

Therefore I wonder if you know or can point where such documents from another groups can be found, I would like to read as many as possible in before I create ours.

It gives an overview of typical content in what he calls a "lab handbook" (despite the different terminology, this is about the type of document you are looking for), plus a list of links to such handbooks which he reviewed to compile this overview.
