How does any one collaborator get credit for his/her contributions?
This is of course a major question... Internal publications within the Collaboration, usually with one or a few authors, will document the individual contributions. These can be made known to the whole scientific community. Also, leading contributions are often recognized by asking the person in question to present results at conferences. However, the large collaborations still have to learn better how to handle this question in a fair way. Often major results are obtained in a collective way, because people are willing to share the tasks.
