Douglas, affectionately known as ‘Duggie' by supporters, made nearly 470 appearances for the club during two spells at Rovers – a record only surpassed by current club favourite James Coppinger.
The Scots born centre forward and defender, now 57, was one of the club’s most popular players during the 80s and early 90s and is still a regular visitor to the club’s matches at the Keepmoat Stadium.
Now his daughter Alicia is calling on supporters to come forward with anecdotes, stories and pictures from her dad’s career.
She said: “He’s starting to write his own book about his life. I want pictures and stories about my dad.
“It would really help as he has forgotten a lot of things and we’re wanting to fill in the gaps.”
His first senior club was Celtic but he made his name at Rovers, joining the club in 1981 and enjoying a successful spell which saw him score 48 goals in 222 appearances.
He later moved across South Yorkshire to Rotherham United, but returned to Doncaster in 1988, scoring five further goals and making 192 appearances.
After leaving Rovers in 1993, he played for Bridlington Town, before becoming player manager of local sides Armthorpe Welfare and Hatfield Main.
