One way is through documentation. We can record the oral histories of the people who worked on these buildings, whether they were architects, engineers or construction workers. This can be done through interviews and archiving them in libraries or online databases.
Museums can also play a role. They can have exhibits dedicated to the construction and history of New York's buildings. For instance, they could display the original blueprints, tools used in construction, and photos of the building process. This would help in preserving the stories for future generations and also educate the public about the rich history of New York's architecture.
Another method is to have guided tours. These can be specialized tours that focus not just on the architecture but on the stories behind the building. For example, a tour of the Woolworth Building could include stories about how it was financed and the significance it held when it was first built. By having knowledgeable guides, the stories can be passed on to visitors.
