Shallan's sketchbook is a collection of sketches she drew throughout the The Way of Kings and now includes those sketches drawn throughout Words of Radiance, some of which decorate the real life interiors of the novels, all of which were drawn by Inkthinker.

In Shallan's eyes, the world is a wondrous place. She hungers to learn more, wishes to observe each and every one of its creatures, to have sketches of them in her books. She even resorts to immersing herself underwater in an effort to observe the rarely seen santhid on her trip aboard the Wind's Pleasure toward the Shattered Plains.[1]

Throughout her trip to Kharbranth Shallan makes drawings of plants and animals she observes, adding her notation on each. Those drawings indicate to Jasnah that Shallan pursues scholarship in her free time for its own sake, which helps Jasnah finalize her decision and grant Shallan's request for apprenticeship.

Among the sketches Shallan makes are those of Jasnah performing Soulcastings of people in the Palanaeum, and various creatures in Kharbranth's palace gardens.
