how can i identify wood siding?

I need to replace some siding,so i need to know what it is. Is there a website or something that can help me? Or should i just post pics here? I know it is not asbestos, fiber, composite. Guessing it is not cedar, no smell. Looks like just pine. Do they make them in just pine? In some spots, the paint has peeled off, but the siding does not appear damaged. Is there a non cedar, wood, weatherproof shingle? They are machine cut, uniform size. House is in CT. Built in 1965. Thanks
