History of Wigan   (Help with ancient and recent history.)

In researching Carnegie libraries in Lancashire I've found one in Ashton in Makerfield but no others. From memory I thought there was a Carnegie children's library in Wigan, which I picture as being near where the later Wigan swimming pool was built. My memory may be at fault on this. Can anyone shed light on Carnegie children's libraries in the Wigan area, i.e. where they are or were?
