I opened the book .obj in Substance painter, and applied the ID maps. I painted in normal for the details on the edges of the pages, and baked these out as I learned in previous models. I then re-opened the book .obj with the normal maps and colour IDs and textured the books with various leather, as well as paper. I added normal details with title stamped using an alpha, with a dark colour beneath to add the darker indented details.
I then opened the .obj file with the books and the shelf, and textured the shelf. I had saved each of the 5 book textures as smart materials, including the normal details with the spine details. I imported the baked normal maps for the books, along with the Colour IDs, before applying my smart materials and exporting. What I hadn’t noticed, was that the detail on the binding had not transferred over inside the smart material.

I am pleased with my final export, and I think it is of a much higher standard than the first attempt. I have used what I learned from the previous mistakes to make a nicely finished piece.
