Could someone kindly detail how to request a recording for viewing at NYPL in Lincoln center?

Really wanted to check out some productions of plays I missed, actually for research purposes since I’m writing a screenplay inspired by them.

Could someone kindly give me pointers where/what to do and what to bring with? And any other tips?

For instance, I only have a E-NYPL bar code, is that enough or do I need a physical library card first? Do I just walk in and ask any librarian for a specific copy by specifying the production details?
