For those of you who happen to be in London this summer, a major exhibit awaits at Lambeth Palace Library. "Treasures of Lambeth Palace Library" opened today as part of the library's 400th anniversary celebration. According to the press materials, it is one of the earliest public libraries in England. Highlights of the exhibition include the warrant for the execution of Mary Queen of Scots, Irish illuminated manuscripts from the ninth century, and several royalty-owned manuscripts and early printed books. Scala Publishers has issued a companion book for those of us who won't make it to the exhibit, running through July 23.
