Sorting books involves organizing them based on specific criteria, such as genre, author, or publication date. This process helps readers easily locate and access the books they want. Libraries and bookstores often use sorting systems to maintain order and improve the browsing experience for customers. In a personal collection, individuals may choose to sort books by fiction and non-fiction, or by alphabetical order based on the author's name. This method not only enhances the aesthetic appeal of a bookshelf but also makes it more functional for finding and enjoying literature.
