SALISBURY, ENGLAND - SEPTEMBER 14: A mouse that was squashed by 19th century pupils at the Cathedral School in a Latin textbook that was published in 1684 is seen preserved in the library at Salisbury Cathedral on September 14, 2016 in Salisbury, England. Starting this month, the cathedral is offering the general public access to the library for the first time with organised guided tours. Although the room housing the library at Salisbury Cathedral was built in 1445 the origins of the library stretch back much further and still contains a large collection of books that were created by the scribes of the old cathedral in the late 11th century which constitutes the largest collection of manuscripts of the Norman period still with its original owner. Today the Library holds approximately 8,000 volumes dating from the ninth century to the present day, with the majority of books being theological and literary texts with further examples of a wide range of other subjects including science, mathematics and medicine.
