Papers about programming languages involve complex notations, systems, and proofs. Static PDFs offer little support in understanding such concepts. We describe Nota, a framework for academic papers that uses the browser’s interactive capabilities to support comprehension in context. Nota uses hover effects, tooltips, expandable sections, toggle-able explanations, and other interactions to help readers understand a language’s syntax and semantics. We demonstrate the use of Nota by rewriting a PL paper using its primitives, and also by writing this paper in Nota.
