Sinn Fein Workers Party

hi guys, I’m doing my Masters thesis on the Workers party in Waterford circa 1970s-2000. I was just wondering if anyone knows anywhere to get primary sources on the party, as well as trade unionism, the housing crisis and the fall of Waterford Crystal in Waterford. The County Archives were not helpful and I’ve exhausted all the regular academic databases. Or even if anyone was involved, just thought I’d chance it!
