OnceWritten.com does reserve the right to feature winning entries on the website and in publications promoting the website for the lifetime of OnceWritten.com. In the case that the work is later re-printed in another publication, OnceWritten.com requests that written credit be given. Authors retain all other rights.
This clause appeared in the terms and conditions of a poetry contest. The author retains her copyright but allows the contest sponsor the non-exclusive right to use the winning entry on the sponsor’s website and in publications promoting the website. The author authorizes these uses for so long as the website remains up. The author should also give credit to the contest sponsor if she republishes the winning poem elsewhere.
