Hi, I am looking to do a study on the M67 cluster, and I would appreciate suggestions on books and articles on the topic and a little bit on open clusters in general. I have found very little information on how M67 affects the dynamics of the galaxy (part of the galaxy neighborhood). There are not many books I can find that have a lot of information on this cluster (granted, it is a relatively "dull" cluster). Any help would be appreciated. Thank you.
