The library of Union Church of Manila began as an outreach of the Women's ministry to the expatriate community. It was staffed by volunteer women of the community, both church members and non-members. In the past, it was not specifically a library for church members, nor was it open on Sundays.

In the mid 1980's the women who then ran the library sought to make it more accessible to the church members by having it open on Sundays a couple of times a month. It was welcomed and successful.

The library had its dedication August 10, 2003.
