Book sharing is a practice where individuals lend or exchange books with others, promoting access to literature without the need for purchasing new copies. This can occur informally among friends or through organized programs like community libraries and book clubs. Many people participate in book sharing to discover new authors and genres while reducing waste. It fosters a sense of community and encourages discussions about literature, making reading a more social experience. Additionally, it can help save money and make books available to those who may not have the means to buy them.
