A sketchbook is usually a loosleaf portfolio or bound volume of paper used by artists as a vital part of the creative process. The Langley Artworks Studio maintains a collection of dozens of these volumes, offering a glimpse into the private studies and evolving ideas of the artist and his journey. These sketches include:  Observations: including documentation of the external world, including travel logs, architectural details, anatomical studies, drawings of the model and nature studies. Memories: including the artist's internal journey, capturing memories, digressions and compositional ideas as they develop into finished works.
