Библиотека и сокровища Эксетерского собора: История и коллекции.

The library began during the episcopate of Leofric (1050–1072) who presented the cathedral with 66 books, only one of which remains in the library: this is the Exeter Book (Exeter Cathedral Library MS 3501) of Anglo Saxon poetry. 16 others have survived and are in the British Library, the Bodleian Library or Cambridge University Library. A 10th century manuscript of Hrabanus Maurus's De Computo and Isidore of Seville's De Natura Rerum may have belonged to Leofric also but the earliest record of it is in an inventory of 1327. The inventory was compiled by the Sub Dean, William de Braileghe, and 230 titles were listed. Service books were not included and a note at the end mentions many other books in French, English and Latin which were then considered worthless. In 1412–13 a new lectrinum was fitted out for the books by two carpenters working for 40 weeks. Those books in need of repair were repaired and some were fitted with chains. A catalogue of the cathedral's books made in 1506 shows that the library furnished some 90 years earlier had 11 desks for books and records over 530 titles, of which more than a third are service books. in 1602, 81 manuscripts from the library were presented to Sir Thomas Bodley for the Bodleian Library at Oxford. In 1657 under the Commonwealth the cathedral was deprived of several of its ancillary buildings, including the reading room of 1412–13. Some books were lost but a large part of them were saved due to the efforts of Dr Robert Vilvaine, who had them transferred to St John's Hospital. At a later date he provided funds to convert the Lady chapel into a library, and the books were brought back. By 1752 it is thought the collection had grown considerably to some 5,000 volumes, to a large extent by benefactions. In 1761 Charles Lyttelton, Dean of Exeter, describes it as having over 6,000 books and some good manuscripts. He describes the work which has been done to repair and list the contents of the manuscripts. At the same time the muniments and records had been cleaned and moved to a suitable muniment room.

Both of the cathedral's towers contain bells. The North Tower contains an bourdon bell, called Peter. Peter used to swing but it is now only chimed. The South Tower contains the second heaviest peal of 12 bells hung for change ringing in the world, with a tenor weighing They are second only to Liverpool Cathedral in weight. There are also two semitone bells in addition to the peal of 12.

One 19th century author claimed that an 11th century missal asserted that King Æthelstan, the previous century, had brought together a great collection of holy relics at Exeter Cathedral; sending out emissaries at great expense to the continent to acquire them. Amongst these items were said to be a little of "the bush in which the Lord spoke to Moses", and a "bit of the candle which the angel of the Lord lit in Christ's tomb". According to the semi legendary tale, the Protestant martyr Agnes Prest, during her brief time of liberty in Exeter before her execution in 1557, met a stonemason repairing the statues at the cathedral. She stated that there was no use repairing their noses, since "within a few days shall all lose their heads". There is a memorial to her and another Protestant martyr, Thomas Benet, in the Livery Dole area of Exeter. The memorial was designed by Harry Hems and raised by public subscription in 1909.

The tube web spider Segestria florentina, notable for its iridescent shiny green fangs, can be found within the outer walls. The walls are made of calcareous stone, which decays from acidic pollution, to form cracks and crevices which the spider and other invertebrates inhabit.

Exeter Cathedral Choir is composed of 38 Choristers (boys and girls) along with Choral Scholars and Lay Vicars. There is also a voluntary choir, the St Peter's singers, dating back to 1881.

Recorded names of organists at Exeter go back to Matthew Godwin, 1586. Notable organists at Exeter Cathedral include Victorian composer Samuel Sebastian Wesley, grandson of Methodist founder and hymn writer Charles Wesley, educator Ernest Bullock, and conductor Thomas Armstrong. The current Director of Music, Timothy Noon, was appointed in 2016.

[[File:Exeter Cathedral 9578. jpg|thumb|upright|The 17th century organ case (enlarged in 1891) The largest pipes, the lower octave of the 32′ Contra Violone, stand just inside the south transept. The organ has one of only three trompette militaire stops in the country (the others are in Liverpool Cathedral and London's St Paul's Cathedral), housed in the minstrels' gallery, along with a chorus of diapason pipes. In January 2013 an extensive refurbishment began on the organ, undertaken by Harrison & Harrison. The work consisted of an overhaul and a re design of the internal layout of the soundboards and ranks of the organ pipes. In October 2014 the work was completed and the organ was reassembled, save for the final voicing and tuning of the new instrument.
