The Compendium gathers the best of the fan submissions, including art, music, crafts, photography and more, displaying some on the website. The very best are chosen by a panel of jurors (including Game of Owns‘ Zack Luye) for inclusion in a printed book. Details can be found in the website’s FAQ.
Some fans voiced concerns regarding the terms and conditions of participation in the Compendium, as the rights HBO retained over the work were initially very broad. Since those criticisms were made, HBO has extensively overhauled the section of terms dealing with the granting of rights to the creative works.
HBO also released this official statement on the matter:
HBO will not be exploring any opportunities to profit off the submitted works. The goal is only to showcase the creativity of Game of Thrones fans. To ease any concerns that may arise, we have altered the legal language to make this clear.
Under the current terms and conditions, creators will retain all ownership to their work, though they do waive the rights to profit from the Compendium. The terms and conditions have removed the words “unrestricted” and “in perpetuity,” which had been a valid cause for concern. The terms are considerably more specific and should make fans more comfortable in submitting, if they would like to be a part of the Game of Thrones Compendium.
