Having made certain decisions about what I was going to concentrate on (book structures as ‘units’, exposed stitching, split sections, fragments of cover, staining, page edges) it was now time to experiment with those details. I sampled different possibilities, identifying exact scale and dimensions and finalising how the work would be presented. These areas were explored alongside each other to some extent. I identified a type of acrylic box divided into units that would sit well within the standard library shelves. I wanted my work to be shown on the shelves, whether that was in amongst the normal book collection or in a gallery space within the library. This acrylic unit (about the scale of a large book) would encase my little books, keeping them safe from disruption by library visitors, whilst enabling viewing from both sides. That containment would also echo the string-bound big book, which cannot be opened: my little books will not be open-able either. The divided acrylic unit had a suggestion of the exposed spine of the big book, which is divided into an uneven grid by the lines of stitching in one direction and the split sections that make up the thick volume in the other. I could fill one of these gridded boxes, or 3, or any number, depending on how long it would take me to make the book units to go within.
