Tony What makes the Presbyterian hymnal 18 volumes is that is hand-transcribed braille on a single side of a page. Adding to the bulk is that the transcribers chose to never begin a verse or chorus on a page unless it could be completed on that page. The LBW, on the other hand, is a press braille book packaged in 3 volumes. Both may contain a similar amount of material; but the LBW is packaged better at least for transportability.
