York Explore libraries will be helping people fill in their online census forms STAFF from Explore York libraries will be teaming up with volunteers from York CVS to help York people fill in their census forms. Explore chief executive Fiona Williams said people can expect to start getting letters about the census on Monday. The letters will invite most people to fill in the census form online - although you will be able to request a paper form if you prefer, Fiona said. Explore staff and CVS volunteers have been getting special training, ready to help anyone who has difficulty filling in the forms, Fiona said.
