Citations, Arrrggghhh!

I am a firm believer in citations, but they are just a huge pain on a project like this. The physical size of the book, each page is about 4 1/4 by 5 1/2 inches, as well as the layout, makes it impossible to properly footnote. On top of that, the font size of the footnotes would be somewhere close to 4. The gut reaction is to switch to end notes, but that would add to many pages and the overall cost of printing would skyrocket to three times the current price. The only reasonably solution is to print up a few properly cited copies of the book and place them in local libraries and keep a few in the rectory. Then on the bottom of the bibliography page in the actual book have a little note that states "For a fully cited copy of this book, please visit...". If anyone has any better ideas, please let me know.
