Stacked Books Outline Illustration

A clean and elegant outline illustration featuring a stack of four books. Each book is depicted horizontally with a rounded spine on the left side, and simple horizontal lines across its length, suggesting pages or text. The design is minimalistic, focusing on essential forms, and has a subtle drop shadow effect against a dark background, giving it a slightly three-dimensional appearance. It effectively conveys the idea of literature, education, or a library in a clear, iconic manner.
