Engelking set a standard for modern topological notation (e.g., using Fr for frontier/boundary, int for interior, cl for closure). Many later textbooks adopted his conventions.
The exercises are not mere homework problems; they are a curated encyclopedia of topological counterexamples and secondary theorems, complete with citations to the original papers (e.g., Aleksandrov, Urysohn, Tychonoff).

Each section ends with bibliographic and historical notes that trace the development of specific theorems.
Even though topology is about abstract spaces, sketching the "rubber-sheet" geometry helps in understanding continuity and separation. Engelking set a standard for modern topological notation (e
If you are diving into a specific topological problem, let me know:
"General Topology" by Engelking is a comprehensive textbook that covers the fundamental concepts and results in general topology. The book is divided into 10 chapters, which provide a thorough introduction to the subject. A deep dive into covering dimension and inductive dimension
Engelking bridges the gap between abstract topology and classical mathematical analysis by deeply analyzing metric spaces. He covers Urysohn’s Metrization Theorem, the Nagata-Smirnov Metrization Theorem, and Bing's Metrization Theorem. 7. Paracompactness and Uniform Spaces
