ARTIST Trevor Stubley is to give a large collection of his material to the West Yorkshire Archive Society.
The Holmfirth artist, whose home, gallery and studio are all in Greenfield Road, has been keeping records for much of his career.
The archive includes copies of more than 400 children's books he has illustrated and photos of every watercolour landscape he painted while travelling around Europe.
Trevor, 72, said: "The copies of the children's books I have illustrated have already been deposited with Kirklees Council. But I have been an obsessive keeper of records all these years.
"I have photographed everything I have ever painted since 1980 and recorded them in a ledger, noting the title, the dimensions, the medium, where it has been exhibited, who owns it and what they paid for it."
Trevor, who believes he has completed about 3,400 paintings since he left Edinburgh College of Art in 1955, was elected a member of the Royal Society of Portrait Painters in the 1980s.
He was commissioned to paint a portrait of the Queen in 1986.
Trevor now wants all the records he has collected during the past 40 years to be available to the public.
He said: "I have generated a massive amount of archival material over the years. I think it appropriate that all this material is kept together in one place, where anyone who is interested would be able to consult it."
The records will be kept at Huddersfield Public Library.
Trevor, whose wife, Valerie, is head of art at Salendine Nook High School, is now concentrating on paintings with a mythological theme.
