History of Thank You for Libraries Day

According to historians, the birth of libraries marked the end of prehistory and the start of history. The first libraries were nothing more than archives for commercial transactions or inventory records. The first libraries appeared in Southwest Asia’s Fertile Crescent, which ran from Mesopotamia to the Nile in Africa about 5,000 years ago. This same area was also the birthplace of writing before 3000 B.C. These libraries contained records written on clay tablets, stacked on edge, side by side. Libraries of the same nature were found in several regions, including Ugarit, China, Nippur, and Nineveh. In the 3rd century B.C., the construction of the Library of Alexandria in Egypt began. The project was sponsored either by Ptolemy I Soter (323 B.C. to 283 B.C.) or his son Ptolemy II (283 B.C. to 246 B.C.). The library became the largest and most significant great library of the ancient world until the Roman conquest in 30 B.C. During this period, the Han Dynasty created three libraries, which featured the first library classification system.

During the Greco-Roman period, libraries thrived under the patronage of wealthy citizens and each succeeding Roman emperor. Asinius Pollio established the first public library in Rome, and his successors added to the number. After the fall of the Roman Empire, the Christian Church became the new power in Europe. Hellenistic texts thought to be pagan were left to decay, and only those related to Christianity survived. However, that was different in Eastern Europe, where monks labored day and night in scriptoriums to preserve Classical Greek and Roman works. In the Muslim world, libraries flourished as the Chinese art of papermaking was acquired. Under the patronage of caliphs and Muslim leaders, important Islamic cities, such as Baghdad, became centers of knowledge and scholarship.

Between the Renaissance and Enlightenment eras, libraries began appearing in some parts of Europe, including Italy and Hungary. These libraries serve as a center for scholars of renown to congregate. Most of these libraries were endowed by prominent individuals, including kings, queens, and popes. At the start of the 18th century, libraries became increasingly open to the public, allowing people to loan books. In 1833, the first tax-supported public library in the U.S. was established in Peterborough, New Hampshire. The library was a joint effort by the Peterborough Town Meeting and state funds from the State Literary Fund.

Between the 19th century and late 20th century, the number of public libraries drastically increased with the support of philanthropists and businessmen, including John Passmore Edwards, Henry Tate, Andrew Carnegie, and Bill and Melinda Gates. In the 21st century, libraries moved from only offering physical collections to providing access to digital resources, including e-books and internet services.
