In order not to let the library die out, Franklin thought it over and came up with a set of practical methods, which were approved by his friends. At that time, according to the plan, for the first batch of 50 readers who applied, the library stipulated that each reader should first pay 40 shillings, and then gradually reduce it to annual donation 10 shillings. After the establishment of the library, a batch of books were purchased from England with the money raised, which was opened every week 1 time. Donors are free to borrow and return them within the prescribed time limit. Not many people love reading, but after the establishment of the library, people's love for books was aroused, and more and more readers came. Many people have donated their books to the library, and many book collectors have donated their treasures collected for many years to the library. At that time, the library was unprecedentedly prosperous, and then it was opened regularly every day. After the news spread, other places followed suit and built libraries. At that time, people liked to walk into the library, which greatly promoted the spread of literature and scientific knowledge in North America at that time. A few years later, gradually funded by the government, private libraries became public, and libraries began to become permanent cultural communication institutions of the government.
