Trying to create a relationship between two spreadsheets

I’m a music director at a church and I have created a spreadsheet with all the hymns from our hymnal. The problem is that I also need a 2nd hymnal that has guitar chords, so I can relate the tunes from the original hymnal to the correct page in the 2nd hymnal. The data from both hymnals have been entered, but I’m at a loss as to how to relate them. Can you offer some suggestions?
