Great little library. Doesn't have most books, but you can always find something to pick up. They also have a small building off to the sides where the book sales happen mid-week. One thing to know, I tried to apply for a library card and the librarian took one look at me and assumed I was not eligible for a library card.
So here's my public service announcement, you can absolutely get a library card regardless of what the librarian might assume or tell you. A permanent one if you live in Peconic or Southold OR a temporary one if you are just visiting.
"Just visiting? You can get a temporary card for the duration of your stay, for unlimited access at the Southold Library."
