British Library in the context of Socage

Sir Hans Sloane, 1st Baronet, FRS (16 April 1660 – 11 January 1753) was an Anglo-Irish physician, naturalist, and collector. He had a collection of 71,000 items which he bequeathed to the British nation, thus providing the foundation of the British Museum, the British Library, and the Natural History Museum, London.

Elected to the Royal Society at the age of 24, Sloane travelled to the Caribbean in 1687 and documented his travels and findings with extensive publications years later. Sloane was a renowned medical doctor among the aristocracy, and was elected to the Royal College of Physicians at age 27. Though he is credited with the invention of chocolate milk, it is more likely that he learned the practice of adding milk to drinking chocolate while living and working in Jamaica. Streets and places were later named after him, including Hans Place, Hans Crescent, and Sloane Square in and around Chelsea, London—the area of his final residence—and also Sir Hans Sloane Square in Killyleagh, his birthplace in Ulster.

A treasure binding or jewelled bookbinding is a luxurious book cover using metalwork in gold or silver, jewels, or ivory, perhaps in addition to more usual bookbinding material for book covers such as leather, velvet, or other cloth. The actual bookbinding technique is the same as for other medieval books, with the folios, normally of vellum, stitched together and bound to wooden cover boards. The metal furnishings of the treasure binding are then fixed, normally by tacks, onto these boards. Treasure bindings appear to have existed from at least Late Antiquity, though there are no surviving examples from so early, and Early Medieval examples are very rare. They were less used by the end of the Middle Ages, but a few continued to be produced in the West even up to the present day, and many more in areas where Eastern Orthodoxy predominated. The bindings were mainly used on grand illuminated manuscripts, especially gospel books designed for the altar and use in church services, rather than study in the library.

The vast majority of these bookbindings were later destroyed as their valuable gold and jewels were removed by looters, or the owners when in need of cash. Others survive without their jewels, and many are either no longer attached to a book, or have been moved to a different book. Some survive in major libraries; for example, the Morgan Library in New York City, the John Rylands Library in Manchester, the British Library in London, the Bayerische Staatsbibliothek in Munich and the Bibliothèque Nationale in Paris. As the carved ivory reliefs often used could not usually be recycled, these survive in much larger numbers, giving a better idea of the numbers of treasure bindings that once existed. Other examples are recorded in documentary sources but though the books survive the covers do not. The Book of Kells lost its binding after a robbery, and the fate of the missing cover of the Book of Lindisfarne is not recorded.

Vellum is prepared animal skin or membrane, typically used as writing material. It is often distinguished from parchment, either by being made from calfskin, rather than the skin of other animals or simply by being of a higher quality. Vellum is prepared for writing and printing on single pages, scrolls, and codices (books).

Modern scholars and experts often prefer to use the broader term "membrane", which avoids the need to draw a distinction between vellum and parchment, as it is very hard to determine the type of animal involved, let alone its age, without detailed scientific analysis.

The Constitution of the Athenians, also called the Athenian Constitution (Ancient Greek: Ἀθηναίων πολιτεία, romanized: Athēnaiōn Politeia), is a work by Aristotle or one of his students. The work describes the constitution of Athens. It is preserved on a papyrus roll from Hermopolis, published in 1891 and now in the British Library. A small part of the work also survives on two leaves of a papyrus codex, discovered in the Fayum in 1879 and now in the papyrus collection of the Egyptian Museum of Berlin.

Prester John (Latin: Presbyter Ioannes) was a mythical Christian patriarch, presbyter, and king. Stories popular in Europe in the 12th to the 17th centuries told of a Nestorian patriarch and king who was said to rule over a Christian nation lost amid the pagans and Muslims in the Orient. The accounts were often embellished with various tropes of medieval popular fantasy, depicting Prester John as a descendant of the Three Magi, ruling a kingdom full of riches, marvels, and strange creatures.

At first, Prester John was imagined to reside in India. Tales of the Nestorian Christians' evangelistic success there and of Thomas the Apostle's subcontinental travels as documented in works like the Acts of Thomas probably provided the first seeds of the legend. As Europeans became aware of the Mongols and their empire, accounts placed the king in Central Asia, and eventually Portuguese explorers came to believe that the term was a reference to Ethiopia, which at that time was an isolated Christian "exclave" distant from any other Christian-ruled territory.

Maryam (Arabic: مريم, Maryam; Arabic cognate of 'Mary') is the 19th chapter (sūrah) of the Qur'an with 98 verses (āyāt). The 114 chapters in the Quran are roughly ordered by size. The Quranic chapter is named after Mary, mother of Jesus (ʿIsa, عیسی), and the Virgin Mary in Christian belief. It recounts the events leading up to the birth of Jesus. The text of the surah refers to many known prophetic figures, including Isaac, Jacob, Moses, Aaron, Ishmael, Idris, Adam, Zechariah and Noah.

The Birmingham Quran manuscript preserves the final eight verses (Q19:91–98), on parchment radiocarbon dated to between 568 and 645 CE (56 BH – 25 AH). The Sanaa manuscript, dated between 578 and 669 CE (44 BH – 49 AH), includes verses 2–28.

The Nowell Codex is the second of two manuscripts comprising the bound volume Cotton MS Vitellius A XV, one of the four major Old English poetic manuscripts. It is most famous as the manuscript containing the unique copy of the epic poem Beowulf. In addition to this, it contains first a fragment of The Life of Saint Christopher, then the more complete texts Wonders of the East and Letter of Alexander to Aristotle, and, after Beowulf, a poetic translation of Judith. Due to the fame of Beowulf, the Nowell Codex is also sometimes known simply as the Beowulf manuscript. The manuscript is located within the British Library with the rest of the Cotton collection.

A national library is a library established by a government as a country's preeminent repository of information. Unlike public libraries, these rarely allow citizens to borrow books. Often, they include numerous rare, valuable, or significant works. A national library is that library which has the duty of collecting and preserving the literature of the nation within and outside the country. Thus, national libraries are those libraries whose community is the nation at large. Examples include the British Library in London, and the Bibliothèque nationale de France in Paris.

There are wider definitions of a national library which put less emphasis on the repository character.

The Estoire d'Eracles ("History of Heraclius") is an anonymous Old French translation and continuation of the Latin History of Deeds Done Beyond the Sea by William of Tyre. It begins with recapture of Jerusalem by the Roman emperor Heraclius in AD 630, from which it takes its name, and continues down to 1184. The continuation recounts the history of the Crusader states from Saladin's capture of Jerusalem in 1187 down to 1277.

The translation was made between 1205 and 1234, possibly in Western Europe. Several times the text of the translation was changed and the manuscripts preserve different versions of William's text. The continuations were added to the translation between 1220 and 1277. There are two different versions of the first continuation, covering the years 1185–1225. Both reflect the political attitudes of the Crusader aristocracy. There are 49 surviving manuscripts of the Eracles. Of these, 44 contain a first continuation drawn from the Chronicle of Ernoul and five (the so-called Colbert–Fontainebleau manuscripts) contain a different version. Twelve of the manuscripts contain a unique continuation for the years 1229–1261 drawn from the independent work known as the Rothelin Continuation.

The Bavarian State Library (German: Bayerische Staatsbibliothek, abbreviated BSB, called Bibliotheca Regia Monacensis before 1919) in Munich is the central "Landesbibliothek", i. e. the state library of the Free State of Bavaria, the biggest universal and research library in Germany and one of Europe's most important universal libraries. With its collections currently comprising around 39.4 million media units (as of 2025), it ranks among the leading research libraries worldwide. The Bayerische Staatsbibliothek furthermore is Europe's second-largest journals library (after the British Library). Furthermore, its historical holdings encompass one of the most important manuscript collections of the world, the largest collection of incunabula worldwide, as well as numerous further important special collections. Its collection of historical prints before 1850 totals almost one million units.

The legal deposit law, still applicable today, has been in force since 1663 and requires that two copies of every printed work published in Bavaria have to be submitted to the Bayerische Staatsbibliothek. The BSB publishes the specialist journal Bibliotheksforum Bayern and has been publishing the Bibliotheksmagazin together with the Berlin State Library between 2007 and 2023. Its building is situated in the Ludwigstrasse.

The Lindisfarne Gospels (London, British Library Cotton MS Nero D.IV) is an illuminated manuscript gospel book probably produced around the years 715–720 in the monastery at Lindisfarne, off the coast of Northumberland, which is now in the British Library in London. The manuscript is considered one of the finest works in the unique style of Hiberno-Saxon or Insular art, combining Mediterranean, Anglo-Saxon and Celtic elements.

The Lindisfarne Gospels are presumed to be the work of a monk named Eadfrith, who became Bishop of Lindisfarne in 698 and died in 721. Current scholarship indicates a date around 715, and it is believed they were produced in honour of St. Cuthbert. However, some parts of the manuscript were left unfinished so it is likely that Eadfrith was still working on it when he died. It is also possible that he produced them prior to 698, in order to commemorate the elevation of Cuthbert's relics in that year, which is also thought to have been the occasion for which the St Cuthbert Gospel (also in the British Library) was produced. The Gospels are richly illustrated in the insular style and were originally encased in a fine leather treasure binding covered with jewels and metals made by Billfrith the Anchorite in the 8th century. During the Viking raids on Lindisfarne this jewelled cover was lost and a replacement was made in 1852. The text is written in insular script, and is the best documented and most complete insular manuscript of the period.

The Dunhuang map or Dunhuang Star map is among the earliest known graphical depictions of the night sky in ancient Chinese astronomy, dating to the Tang dynasty (618–907). Prior to the discovery of this map, much of the star-related information recorded in early Chinese texts had been subject to speculations. The map provides visual corroboration of those textual records and forms part of a scroll that includes a series of illustrations found among the Dunhuang manuscripts. It is currently regarded as the world's oldest known complete star atlas.

The manuscript containing the star map was discovered in the early 20th century in the Mogao Caves and was taken along with hundreds of other manuscripts during a British expedition to Dunhuang. The scroll containing the Dunhuang map is currently held in the British Library.

Constantine Manasses (Greek: Κωνσταντῖνος Μανασσῆς; c. 1130 – c. 1187) was a Byzantine chronicler who flourished in the 12th century during the reign of Manuel I Komnenos (1143–1180). He was the author of a Synopsis Chronike (Σύνοψις Χρονική, "summary chronicle"), which narrates history from the creation of the world to the end of the reign of Nikephoros III Botaneiates (1081), sponsored by Irene Komnene, the emperor's sister-in-law. It was probably written around 1150, shortly before Irene's death.

It consists of about 7,000 lines in political verse. It obtained great popularity and appeared in a free prose translation. It was translated into Bulgarian in the 14th century. This translation, which includes several miniatures, was commissioned by tsar Ivan Alexander between 1340 and 1345. An Arabic translation written in 1313 is now hosted at the British Library.

Woodblock printing or block printing is a technique for printing text, images or patterns used widely throughout East Asia and originating in China in antiquity as a method of printing on textiles and later on paper. Each page or image is created by carving a wooden block to leave only some areas and lines at the original level; it is these that are inked and show in the print, in a relief printing process. Carving the blocks is skilled and laborious work, but a large number of impressions can then be printed.

As a method of printing on cloth, the earliest surviving examples from China date to before 220 AD. Woodblock printing existed in Tang China by the 7th century AD and remained the most common East Asian method of printing books and other texts, as well as images, until the 19th century. Ukiyo-e is the best-known type of Japanese woodblock art print. Most European uses of the technique for printing images on paper are covered by the art term woodcut, except for the block books produced mainly in the 15th century.

The Epistle to the Colossians is a Pauline epistle and the twelfth book of the New Testament of the Christian Bible. It was written, according to the text, by Paul the Apostle and Timothy, and addressed to the church in Colossae, a small Phrygian city near Laodicea and approximately 100 miles (160 km) from Ephesus in Asia Minor (now in Turkey).

Many scholars question Paul's authorship and attribute the letter to an early follower instead, but others still defend it as authentic. If Paul was the author, he probably used an amanuensis, or secretary, in writing the letter (Col 4:18), possibly Timothy.

The Plumb-pudding in danger, or, State Epicures taking un Petit Souper is an 1805 editorial cartoon by the English artist James Gillray. The popular print depicts caricatures of the British Prime Minister William Pitt the Younger and the newly-crowned Emperor of France Napoleon, both wearing military uniforms, carving up a terrestrial globe into spheres of influence. It was published as a hand-coloured print and has been described by the National Portrait Gallery as "probably Gillray's most famous print" and by the British Library as "one of Gillray's most famous satires dealing with the Napoleonic wars".

The Charter of the Forest of 1217 re-established rights of access for free men to the royal forest that had been eroded by King William the Conqueror and his heirs. Many of its provisions were in force for centuries afterwards. It was originally sealed in England by the young King Henry III, acting under the regency of William Marshal, 1st Earl of Pembroke.

It was in many ways a companion document to Magna Carta. The charter redressed some applications of the Anglo-Norman Forest Law that had been extended and abused by King William Rufus.

A scriptorium (/skrɪpˈtɔːriəm/ ) was a writing room in medieval European monasteries for the copying and illuminating of manuscripts by scribes.

The term has perhaps been over-used—only some monasteries had special rooms set aside for scribes. Often they worked in the monastery library or in their own rooms. Most medieval images of scribing show single figures in well-appointed studies, although these are generally author portraits of well-known authors or translators. Increasingly, lay scribes and illuminators from outside the monastery also assisted the clerical scribes. By the later Middle Ages secular manuscript workshops were common, and many monasteries bought more books than they produced themselves.

The Laṅkāvatāra Sūtra (Sanskrit: लङ्कावतारसूत्रम्, "Discourse of the Descent into Laṅkā", Standard Tibetan: ལང་ཀར་བཤེགས་པའི་མདོ་, Chinese: 入楞伽經) is a prominent Mahayana Buddhist sūtra. It is also titled Laṅkāvatāraratnasūtram (The Jewel Sutra of the Entry into Laṅkā, Gunabhadra's Chinese title: 楞伽阿跋多羅寶經 léngqié ābáduōluó bǎojīng) and Saddharmalaṅkāvatārasūtra (The Sutra on the Descent of the True Dharma into Laṅkā). A subtitle to the sutra found in some sources is "the heart of the words of all the Buddhas" (一切佛語心 yiqiefo yuxin, Sanskrit: sarvabuddhapravacanahṛdaya).

The Laṅkāvatāra recounts a teaching primarily between Gautama Buddha and a bodhisattva named Mahāmati ("Great Wisdom"). The sūtra is set in mythical Laṅkā, ruled by Rāvaṇa, the king of the rākṣasas. The Laṅkāvatāra discusses numerous Mahayana topics, such as Yogācāra philosophy of mind-only (cittamātra) and the three natures, the ālayavijñāna (store-house consciousness), the inner "disposition" (gotra), the buddha-nature, the luminous mind (prabhāsvaracitta), emptiness (śūnyatā) and vegetarianism.
