Hi William 1000
Youre right, Paisley Library has a very good collection of local stuff including censuses and OPR films for all of Renfrewshire.
They have a very good collection of local maps too and the staff are very helpful.
There is a section on local history which has some MIs for the area and info on local industries.
Its all in the reference section, not the main library.
I haven't had to book a machine yet particularly if you get there early (opens at 10.00) and you can get photocopies from the microfiche reader and the film reader at reasonable cost.
