From time to time I need to reference Heidi Johnson's work published as part of the LREC workshops in 2002 and 2006 under the title: "International Workshop on Resources and Tools in Field Linguistics". The papers never got hosted on the official LREC website. Rather the papers were hosted on the MPI website.
Who do I talk to about getting these papers into the https://aclanthology.org database of papers. They would get the attention they need in that paper repository.
