For many years the library was located on Chiltern Street in central London.

In this aim he was much encouraged in 1938 by the then associate minister of Westminster Chapel, Dr Martyn Lloyd-Jones.

Before the move in 1944 to its Chiltern Street location close to Baker Street Underground station, it was known as the Beddington Free Grace Library, based in the tiny village of Beddington, Surrey.

It hosts an annual lecture and publishes a regular magazine called In Writing (formerly known as The Evangelical Library Bulletin).

Following a major refurbishment in 2005, the library now has a reference room, known as the Robert Sheehan Puritan and Research Centre,[2] named in honour of the late Robert J. Sheehan (1951–97), the former pastor of Welwyn Evangelical Church.
