is the main research library of
the University of Oxford.
"The Bodleian Library occupies a group of five buildings near Broad Street: these range in date from the late medieval Duke Humfrey's Library to the New Bodleian of the 1930s" (wiki source). continue...
"Whilst the Bodleian Library, in its current incarnation, has a continuous history dating back to 1602, its roots date back even further. The first purpose-built library known to have existed in Oxford was founded in the fourteenth century by Thomas Cobham, Bishop of Worcester. This small collection of chained books was situated above the north side of the University Church of St Mary the Virgin on the High Street. This collection continued to grow steadily, but when, between 1435 and 1437 Humphrey, Duke of Gloucester (brother of Henry V of England), donated a great collection of manuscripts, the space was deemed insufficient and a larger building was required. A suitable room was finally built above the Divinity School, and completed in 1489. This room continues to be known as Duke Humfrey’s Library" (HB.com).
Here is posted information about the release of images and has provided other links- "You can jump into the entire collection here, or view a set of highlights here." And an excellent blog about this collection.

Below are photos from the exterior of the library. Unfortunately we arrived too late and were not able to enter. The interior photo is from Oxford University. Intricate, web ceilings, such as the one pictured, are the height (excuse the pun) of Gothic. There's plenty to see in Oxford, however some very, very cool manuscripts and rare books are located here.
