The font is a commercial font from Emigre
and it is called Suburban Light

You are welcome.
It has been used in recent years on a few trade books - it is how I came to know it. It has some very distinctive characters, however it is a Display face, and not meant for large text files.
Enjoy using it.
can someone identify this font?
