Ryszard Engelking's is widely considered the "bible" of the field, serving as both a comprehensive textbook and a definitive reference for researchers.
and paracompactness : Paracompactness is thoroughly explored due to its vital role in the existence of partitions of unity, which are essential for differential geometry and topology. 6. Dimension Theory (Chapter 7)

This comprehensive article explores the book's structure, why it remains the gold standard in mathematical literature, its core chapters, and how to utilize it effectively in your studies.
General topology, also known as point-set topology, is a branch of mathematics that studies the properties of topological spaces. These properties are preserved under continuous deformations, such as stretching and bending, but not tearing or gluing.
The 1989 edition is still under copyright. Heldermann Verlag holds the rights. Unlike older works (e.g., Kelley’s 1955 text which is in the public domain in some jurisdictions), Engelking is not legally free.
Each chapter concludes with a massive section of exercises—not simple "check your understanding" problems, but research-level challenges. Many of these problems contain results that are not found in any other textbook. Working through Engelking’s problems transforms a student from a passive learner into an active researcher.
