Getting info from county clerk office

[Tanya Potter]

any advice on how to navigate the county clerk website for nyc particularly Queens? I found a few properties I want to look into when I was driving for dollars but I am having a lot of trouble getting info on the owner. Houses look vacant so I'm trying to find the address where tax docs are sent. I've also called the office and they were very unhelpful. Just told me they didn't know how to find the info.
