While many authors, ("e.g." Neil Gaiman, J.K. Rowling, D.J. MacHale, Stephenie Meyer, Terry Pratchett) do not take issue with authors of derivative works, a number of authors do. They may request that fan fiction archival sites remove and ban any pieces of fan fiction based on their original works. To date, no fan fiction archive has failed to comply with an author's request to remove works, and many archives feature a full list of authors whose work cannot be the source of a fan fiction on their site.
