The Kedermister Library, at Langley near Slough in the English county of Berkshire (formerly Buckinghamshire), is a rare surviving example of an early 17th-century parish library, preserved in situ in the decorated cupboards designed for it in 1620 in the parish church of St Mary the Virgin.
The original vellum catalogue dated in 1638, is still hanging in the library.
The library and pew still exists and, with the contemporary catalogue, provides insight into scholarship and book collecting in the 17th century.
The library is only open to the public on the first of the month from March to October, and by personal appointment any time of the year.
[2] The name Kedermister is the most commonly used, though some sources, including the charity governing the library, use the spelling Kederminster.
