If you decide to go ahead, have a clear view of what the role of the committee should be. Make it clear what power they will have and what duties they will perform. Meetings such as this can suddenly have a collective rush of blood to the head, and charge off in a direction that is as dangerous as it is unexpected. Take time to plan, producing written reports to back up your proposals and undertaking personal lobbying on the more important issues. Altruism is a rare commodity, so people who sit on such committees tend to want something in return. Sometimes you will get away with giving them a bland meeting and an exciting meal (better than the other way round). Unless editors are also owner-publishers, they are inevitably responsible to a more powerful individual or organization. Editorial integrity Clearly editors are unable to act completely freely. They have legal constraints (though it is part of their role to push against these). They have responsibilities to readers to publish material that is accurate and true, as far as is reasonably possible. Finally, they have a responsibility towards the owners (or owner) who fund the publication, and have a right to expect that it does not actively oppose their interests. An editor must have the right to edit, in other words have the last word on what is or is not published. At the same time, the owners have the right to change editors if they feel he or she has taken the wrong decisions. Editing therefore becomes the 43 THE A–Z OF MEDICAL WRITING art of the possible, and one of the main tasks is to ensure that he or she can carry out the actions needed to fulfil their vision.
