I love to read novels and as I read so much, I always tend to the digital copy. But this only applies to novels and books I only will read once. As you I love to hold books about art and craft in my hands for reference. The hardcopy form is much more convenient if I am browsing after techniques... so I may have a shelf of sewing and knitting books and I am always on the hunt for more :-DDDD
I congratulate youth your bargain finds and look forward which projects you will tackle.
