Is there a way to posthumously create a collection for a creator on AO3?

You can posthumously create a collection for a creator through AO3’s memorial archives. In order to do this, you must be the creator’s next of kin or their designated fannish next of kin. Requests for memorial collections can be sent directly through our contact form. After we receive this form, we can begin the process. This process entails both you and a member of Open Doors signing a Memorandum of Understanding which details the terms of the import, announcing the memorial collection, and creating an archivist account for you from which you will upload the works.
