This hymnal: http://www.hymnary.org/hymnal/PS1912, appears to be the same as the United Presbyterian Church hymnal I found here http://books.google.com/books?id=Wm0Cl8tI8KgC&dq=the%20psalter%201912&lr&as_brr=1&pg=PA453#v=onepage&q&f=false.
I can't find any record of a CRC Psalter Hymnal from 1912 outside of this site. Do you know where that information came from?
If the pdf of the Google Books scanned copy can be broken up, could it then be put on this site? Google seems to have a policy against commercial use, but would that apply to this?
