Many people, especially students, haven’t had an opportunity to collaborate with other researchers. Collaboration, especially with remote people can be tricky. Here are some observations of what has worked for me on collaborations involving a few people.

1. Travel and Discuss Almost all collaborations start with in-person discussion. This implies that travel is often necessary. We can hope that in the future we’ll have better systems for starting collaborations remotely (such as blogs), but we aren’t quite there yet.
2. Enable your collaborator. A collaboration can fall apart because one collaborator disables another. This sounds stupid (and it is), but it’s far easier than you might think.
   1. Avoid Duplication. Discovering that you and a collaborator have been editing the same thing and now need to waste time reconciling changes is annoying. The best way to avoid this to be explicit about who has write permission to what. Most of the time, a write lock is held for the entire document, just to be sure.
   2. Don’t keep the write lock unnecessarily. Some people are perfectionists so they have a real problem giving up the write lock on a draft until it is perfect. This prevents other collaborators from doing things. Releasing write lock (at least) when you sleep, is a good idea.
   3. Send all necessary materials. Some people try to save space or bandwidth by not passing ‘.bib’ files or other auxiliary components. Forcing your collaborator to deal with the missing subdocument problem is disabling. Space and bandwidth are cheap while your collaborators time is precious. (Sending may be pass-by-reference rather than attach-to-message in most cases.)
   4. Version Control. This doesn’t mean “use version control software”, although that’s fine. Instead, it means: have a version number for drafts passed back and forth. This means you can talk about “draft 3” rather than “the draft that was passed last tuesday”. Coupled with “send all necessary materials”, this implies that you naturally backup previous work.
3. Be Generous. It’s common for people to feel insecure about what they have done or how much “credit” they should get.
   1. Coauthor standing. When deciding who should have a chance to be a coauthor, the rule should be “anyone who has helped produce a result conditioned on previous work”. “Helped produce” is often interpreted too narrowly—a theoretician should be generous about crediting experimental results and vice-versa. Potential coauthors may decline (and senior ones often do so). Control over who is a coauthor is best (and most naturally) exercised by the choice of who you talk to.
   2. Author ordering. Author ordering is the wrong thing to worry about, so don’t. The CS theory community has a substantial advantage here because they default to alpha-by-author ordering, as is understood by everyone.
   3. Who presents. A good default for presentations at a conference is “student presents” (or suitable generalizations). This gives young people a real chance to get involved and learn how things are done. Senior collaborators already have plentiful alternative methods to present research at workshops or invited talks.
4. Communicate by default Not cc’ing a collaborator is a bad idea. Even if you have a very specific question for one collaborator and not another, it’s a good idea to cc everyone. In the worst case, this is a few-second annoyance for the other collaborator. In the best case, the exchange answers unasked questions. This also prevents “conversation shifts into subjects interesting to everyone, but oops! you weren’t cced” problem.

These practices are imperfectly followed even by me, but they are a good ideal to strive for.
