World ParaVolley has made a call for items and memorabilia which could be included in a museum dedicated to the sport.
The organisation is working to set-up a ParaVolley museum and has also been offered space for a display at the International Volleyball Hall of Fame in Holyoke in Massachusetts.
"We are therefore wishing to compile a list of materials/items that people wish to donate to either place," World Para Volley said.
Sitting volleyball, the current Paralympic discipline, has been a full sport on the programme since the 1980 Games in Arnhem in The Netherlands.
Women have competed since Athens 2004.
In April, World ParaVolley celebrated the 40-year anniversary of the Arnhem Games.
Standing volleyball was also a Paralympic sport between 1976 and 2000.
