No. 11 was occupied by Thornton's bookshop from 1870 to 2002. The building dates from about 1800, and is Grade II listed (ref. 1485/170). Joseph Thornton opened his first bookshop in Magdalen Street in 1835, and moved to 51 High Street in 1840. In 1853 he moved back to Magdalen Street, and in 1863 to 10 Broad Street next door to this shop. In 1870 he moved to No. 11, and his bookshop continued to flourish here as a family firm for over a hundred  years. The photograph of the Buttery, left, was taken before February 2019 when the shop was rebranded as The Shop of Secrets (Harry Potter etc...) and in 2022 as the Outlet Store (store ?)

In 1772 a survey of every house in the city was taken in consequence of the Mileways Act of 1771.
The house then standing on this site was in the occupation of a Mr Sandal, and its frontage measured
5 yards 1 foot 10 inches.

The 1841 census shows the tailor William Wallington at this house. In 1851 the occupant was another
William Wallington, his son of 19, described as a tailor and draper, with his 17-year-old brother as his
assistant. The two teenage drapers live by themselves in the house with a servant and a lodger.

The 1881 census shows Joseph Thornton, who was born in Billericay, as the employer of one man and three boys. Aged 74, he was living over this shop with his wife Clara and daughter Lydia (a governess), and one general servant. His son James was managing a bookshop of his own at 33 High Street at this time.This bookshop, also a publishing house later merged again with the original firm. The business remained in the family until 1983, when it was about to go bankrupt. Wim & Scharlie Meeuws of Holdan Books bought it from John (known as "Young Jack") Thornton, the fourth generation Thornton (although John explained that he should really be regarded as the fifth generation since Joseph started the business with money from his father, a vicar ) This was at the request of some leading members, heads of Oxford colleges of Oxford University. As they put it " Please safe Thornton's for Oxford". The Meeuws family altered the shop between 1983 and 1985 to meet fire regulations. The Thornton's name remained in Broad street until the business finally moved out on 1 January 2003, making place for the Buttery owned by the Moss family.  In early 2019 this was rebranded as The Shop of Secrets  and in 2022 as the Outlet Store (store ?)     Thornton's Bookshop still survive as a mail order and internet company in  Faringdon / Oxfordshire. But in early 2019 most of the stock was sold via various auction houses in the UK and abroad. the bookshop continues to give advice to former customers who wish to sell their library, JUST ASK AND SEND AN E-MAIL
