This is a remarkable publication, not only for its size but for the breadth of its undertaking. I'm going to let the very able description from Printed Matter, where I purchased it, serve as the explanation for this work.
"For several years Monica Ursina Jäger has been drawing built and natural landscapes inspired by Modernist-style architecture. Her precise works, using media including ink and pigment transfers, combine hope and downfall: on one hand designers’ aspirations, and fantasies, for the future; on the other the dystopia of failure. In creating these works Jäger has assembled a huge stock of images of buildings and environments, both her own photographs and images found in print and online, including rendered as well as completed constructions. Topographies, which is created in collaboration with Winfried Heininger, consists of one, extremely long, accordion-folded image created from hundreds of collaged images from this working archive.
