The Library of Congress is the research library that officially serves the United States Congress, but which is the de facto national library of the United States. It is the oldest federal cultural institution in the United States. The Library is housed in three buildings on Capitol Hill in Washington, D.C. The library is the second-largest library in the world by collection size.
The Library of Congress moved to Washington in 1800, after sitting for eleven years in the temporary national capitals of New York and Philadelphia. The small Congressional Library was housed in the United States Capitol for most of the 19th century until the early 1890s. Most of the original collection had been destroyed by the British in 1814 during the War of 1812. To restore its collection in 1815, the library bought from former president Thomas Jefferson his entire personal collection of 6,487 books.
After a period of slow growth, another fire struck the Library in its Capitol chambers in 1851, again destroying a large amount of the collection, including many of Jefferson's books. The Library of Congress then began to grow rapidly in both size and importance after the American Civil War and a campaign to purchase replacement copies for volumes that had been burned from other sources, collections and libraries (which had started to appear throughout the burgeoning United States). The Library received the right of transference of all copyrighted works to have two copies deposited of books, maps, illustrations and diagrams printed in the United States. It also began to build its collections of British and other European works and then of works published throughout the English-speaking world.
This development culminated in the construction between 1888 and 1894 of a separate, extensive library building across the street from the Capitol, in the Beaux Arts style with fine decorations, murals, paintings, marble halls, columns and steps, carved hardwoods and a stained glass dome. It included several stories built underground of steel and cast iron stacks.References:
The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
