The first known catalog of the world is believed to have been created by the ancient Egyptians around 3,000 years ago. The catalog, known as the Alexandria Library, was created by Ptolemy I Soter, who was the ruler of Egypt in the 3rd century BCE. The library was located in Alexandria, Egypt, and it was one of the most famous libraries of the ancient world. The Alexandria Library was considered to be the first known public library in the world and it held a vast collection of books and manuscripts from all over the world, covering a wide range of subjects including literature, science, philosophy, and history. The catalog of the library was said to have been divided into several sections, each of which was dedicated to a specific subject, and it was organized using a system of classification and organization similar to the modern Dewey Decimal Classification system.
It’s worth noting that the Alexandria Library was not the only library that existed in the ancient world, but it was the most famous and most comprehensive of its time. The library was destroyed several times and the catalog and the books were lost, but it remains an important part of history and a symbol of the value of knowledge and learning.
