The NYC LGBT Historical Sites Project has created a map of significant landmarks for the gay rights movement across New York City.

"If there is a kid out there who is looking online for the history of trans people, they can go on our website," says Ken Lustbader, who took part in the project. "It can give them a sense of hope and inclusiveness."

In Brooklyn, sites include the Green-Wood Cemetery, the residences of Walt Whitman, Oliver Smith and Truman Capote, the Transy House and the Lesbian Herstory Archives in Prospect Park.

"People can feel like they are connected to history, like they come from somewhere," says Rebecca Arciprete, a manager of the archives. "It helps give people hope."

Herstory is reputedly home to the world's largest collection of materials by and about lesbians and their communities. Visitors say it's a symbol of love.
