Ebook: General Topology

I found Engelking a difficult book to study general topology from, but an excellent reference book. Engelking covers wide areas of General topology, starting from the basic definition. At times the exposition seemed to veer into too much technicalities, which seemed to distract one, if one was reading the book alone. What makes the book truly great, however, is its index, and bibliography. It's wealth of examples and counterexamples is very useful, as well.

Finally, the Russian translation seems to be enriched with the comments of translators and more bibliography.
