Paul E. Long’s An Introduction to General Topology is a well-regarded, upper-undergraduate level textbook. It strikes a balance between rigorous proof-based mathematics and clear exposition. Compared to heavier classics like Munkres or Kelley, Long’s book is often praised for being more accessible to a first-time learner while still covering essential topics thoroughly.
Because the book was published in 1971, it predates the widespread digitization of academic texts. While this makes it a valuable classic, it also means it is less likely to have been officially scanned and released as a free PDF compared to a more modern open-access textbook.
