Castles of knowledge affected the history
From the dawn of history, people always need a collection of knowledge materials, that are easily accessible to use and to reach. It is responsible to satisfy scientific needs. These collections are called libraries. These libraries were always acted like a symbol of science and knowledge.
Libraries
2600 BC to Present
The history of libraries began with the first efforts to organize collections of documents. Topics of interest include accessibility of the collection, acquisition of materials, arrangement and finding tools, the book trade, the influence of the physical properties of the different writing materials, language distribution, role in education, rates of literacy, budgets, staffing, libraries for specially targeted audiences, architectural merit, patterns of usage, and the role of libraries in a nation's cultural heritage, and the role of government, church or private sponsorship. Since the 1960s, issues of computerization and digitization have arisen. Library history is the academic discipline devoted to the study of the history of libraries; it is a subfield of library science and of history.

The library's functions are overseen by the librarian of Congress, and its buildings are maintained by the architect of the Capitol. The Library of Congress is one of the largest libraries in the world.
Library of Alexandria
280s BC to 642
The Great Library of Alexandria in Alexandria, Egypt, was one of the largest and most significant libraries of the ancient world. The Library was part of a larger research institution called the Mouseion, which was dedicated to the Muses, the nine goddesses of the arts. The idea of a universal library in Alexandria may have been proposed by Demetrius of Phalerum, an exiled Athenian statesman living in Alexandria, to Ptolemy I Soter, who may have established plans for the Library, but the Library itself was probably not built until the reign of his son Ptolemy II Philadelphus. The Library quickly acquired many papyrus scrolls, due largely to the Ptolemaic kings' aggressive and well-funded policies for procuring texts. It is unknown precisely how many such scrolls were housed at any given time, but estimates range from 40,000 to 400,000 at its height.
