The song was first published in 1981 by North American Liturgy Resources. Today copyright is owned by Schutte and OCP Publications.
There has been some controversy because of the way the song is constructed. It was most likely intended for cantor with the congregation singing the chorus: the verses are written in the voice of God "I the Lord of ..." and ending with a question "Whom shall I send", and the chorus responding "Here I am Lord, is it I Lord" in the listener's voice. Despite this, the song is very widely known, sung in full by many congregations, and has crossed denominational boundaries and is now used in a wide variety of Christian churches.
With meter 22.214.171.124 D with refrain, the tune is usually simply called HERE I AM LORD. It has a 4/4 time signature, and in the key of G the first few notes are GF G D C DD.

The song has three verses, and a chorus which is repeated after each verse. A rough outline is:
1 I, the Lord of sea and sky ... whom shall I send?
Here I am Lord. Is it I Lord?
I have heard you calling in the night.
I will go Lord, if you lead me.
I will hold your people in my heart.
2 I, the Lord of snow and rain ...
3 I, the Lord of wind and flame ...
