The building at 945 Summit Avenue in the Bronx was once the headquarters of H.W. Wilson, a publishing company, known for its Readers Guide to Periodical Literature. The lighthouse was part of the company logo, symbolizing the mission of H.W. Wilson: “To give guidance to those seeking their way through the maze of books and periodicals, without which they would be lost.” It’s now the headquarters of Tuck-it-Away storage.
