Choral Public Domain Library was created in 1998.
It depends on what you are looking for. The Choral Public Domain Library [cpdl.org] is a good bet if you're looking for classics; so is the Petrucci Music Library [imslp.org]. These are good resources if you are looking for music in the public domain, which is typically pre-twentieth century. Music from the twentieth century on is typically copyright-protected. Some composers have chosen to give their music away, such as Sally Deford [defordmusic.com], a Christian composer. The Choral Public Domain Library also has several pieces that have been put in the public domain by their composers. If you still cannot find the type of music you would like for free, then you should consider the options of writing your own or paying a fee. Beware searching the internet for free music; you may find what you're looking for, but that does not make it legal.
