One of the things that digital content makes obvious is that the current physical manifestation of a print-bound textbook is a strangely awful construct — one designed to remove students one step (at least one step) from the primary sources that inform the field they’re studying. You don’t read Darwin; you read “Introduction to Biology.” You don’t read de Tocqueville; you read “American History I.” Sure, textbooks offer easier-to-digest summaries of the content, geared to the particular grade level of the student. They offer diagrams and illustrations and review questions and a glossary. But textbooks are always an assembly from a variety of sources, geared towards a classroom setting where the teacher leads students through the chapters and the exercises and the examinations. Neither the teacher nor the student is expected to be an expert. You just need to know enough to pass the test.
