If you have spent any time in graduate-level mathematics forums or asked a topologist for a "tough but rewarding" text, you have inevitably heard the whisper: Dugundji .

Is it outdated? In typesetting, yes. In mathematical rigor, no. Dugundji’s topological foundation is still the bedrock for many working topologists. Topology -Dugundji-.pdf

Recently, I managed to get my hands on a scanned copy of (the classic Allyn & Bacon, 1966 edition). After spending a few weeks working through its pages, I feel like I have wrestled with a mathematical griffin. Here is my honest take on why this book is simultaneously revered and feared. The First Impression: Dense and Proud Unlike the friendly, conversational tone of Munkres (which is the standard for most undergrads), Dugundji assumes you are an adult. The PDF opens not with hand-holding, but with a brisk introduction to classes and proper classes —a nod to the Kelley/Mac Lane school of thought.
