Missing titles in LIBRARY

Kee Lau

When I clicked the LIBRARY and typed "subject:Zechariah", there was one book missing: Klein, George L. Zechariah. Vol. 21B of The New American Commentary. Nashville, TN: B & H Publishing Group, 2008.

I believe there would have been lots of books missing like this. Could you correct the problem?
