While an official, free PDF of Paul E. Long's An Introduction to General Topology does not exist, the book is far from inaccessible. It's a well-respected classic with a proven structure for learning the fundamentals of point-set topology. Your best bets for accessing it are through a university library or by purchasing a used copy. Avoid unreliable download sites, which often lead to different books by authors with similar names. With a little effort, this 1971 classic can be a valuable part of your mathematical journey.
It assumes only a basic familiarity with set theory and standard introductory analysis, making it an excellent first or second-semester textbook for undergraduate mathematics majors.
A critical property that generalizes the concept of closed and bounded intervals in real analysis.

Paul E. Long’s An Introduction to General Topology remains a stellar benchmark for clear, deductive mathematical writing. Whether you find a physical copy or access a digital version through an academic archive, it will provide a rock-solid foundation for your mathematical journey.
While the book focuses on general topology, Long dedicates significant space to metric spaces. Here, the topology is generated by a specific distance function (metric). This acts as a beautiful full-circle moment for students, showing how the abstract definitions of openness and continuity map directly back to the familiar metrics used in calculus.

definition of continuity into the elegant topological definition: a function is continuous if the inverse image of every open set is open. The text thoroughly explores —bijective, bi-continuous functions that prove two topological spaces are topologically "identical" or isomorphic. 4.
