Reference for general-topology Though there are several posts discussing the reference books for topology, for example best book for topology.
But as far as I looked up to, all of them are for the purpose of learning topology or rather on introductory level.
I am wondering if there is a book or a set of books on topology like Rudin's analysis books, S.Lang's algebra, Halmos' measure (or to be more updated, Bogachev's measure theory), etc, serving as standard references.
Probably, such a book should hold characteristics such as being self-contained, covering the most of classical results, and other good properties you can name.
In the end, I only have the interest on general-topology (topological space, metrization, compactification...), and optionally differential topology (manifolds). So please don't divert into algebraic context.
Cheers.

Thanks for all the delightful replies.
I will try to quickly check the books mentioned beneath.
And I may accept the answer which is most closed to my personal flavor.
Sorry for others.
It's a pity no multiple acceptance can be made for such a ref-request question.
Greetings.
 A: The Handbook of Set-Theoretic Topology is a great reference on many advanced areas of general topology.
A: Please look at "Topology and groupoids", 
http://www.bangor.ac.uk/r.brown/topgpds.html
which is published privately to keep the price down, and an e-version for £5 is available through  the above site.  
The first part is a geometric account of general topology, with motivation for definitions and theorems, starting with the neighbourhood axioms, as more intuitive, and then proceeding to open sets, etc. There is a gradual introduction to universal properties, so that topologies are often defined  in order to be able to construct various kinds of continuous functions. It has a lot on identification spaces, adjunction spaces, finite cell complexes, and also an introduction to a topology on function spaces to give a convenient category of spaces. 
The second part is on the use of the fundamental groupoid in algebraic topology, allowing more powerful theorems with simpler proofs. 
A review is at

As said elsewhere on this site, it does not cater so well for the needs of analysts, but they also ought to know about universal properties!  
A: A really nice book about general topology is "Topology" by "James Dugundji". For those who can read portuguese I'd recommend "Elementos de Topologia Geral" by "Elon Lages Lima" - a great book.
A: For general topology, it is hard to beat Ryszard Engelking's "General Topology".  It starts at the very basics, but goes through quite advanced topics.  It may be perhaps a bit dated, but it is still the standard reference in general topology.
A: Bourbaki's General Topology is in my opinion the best reference on General Topology. (The English version has two volumes.) 
A: Kazimier Kuratowski has written a two volume treatise on Topology which focuses more on General Topology. There is also an English translation available. I did not read it entirely, but by reading a few excerpts and looking through the contents it seems to be quite comprehensive.
A: Stephen Willard, General Topology
This book is less complete than Engelking, but still contains enough material to make a good reference book. It is also quite cheap, as a Dover book.
A: One other old stand-by is J.L. Kelley's General Topology, published as GTM 27. It is quite good especially if you are approaching the topic with the eye of an analyst. (In the preface he professed that he wanted to subtitle the book "What Every Young Analyst Should Know".) 
A: Another book which might be worth mentioning in this context (although this is different from other books mentioned here; it contains overview of many various areas, but no proofs of the results given there):

Encyclopedia of General Topology; Edited by: Klaas Pieter Hart, Jun-iti Nagata and Jerry E. Vaughan, Elsevier, 2003, ISBN: 978-0-444-50355-8. sciencedirect, Elsevier, MR2049453, Zbl 1059.54001 .

Many of the authors provide the chapters which their contributed to this book freely on their websites.
Quote from the preface:

Thus the book provides a source where the specialist and nonspecialist
  alike can find short introductions to both the basic theory and the
  newest developments in General Topology.
Because the book is designed for the reader who wants to get a general
  view of the terminology with minimal time and effort there are very few proofs
  given; on occasion a sketch of an argument will be given, more to illustrate a
  notion than to justify a claim.
A reader who wants to study
  the subject matter of one or more of the articles systematically (or who wants
  to see the proof of a particular result) will find sufficient references at the end
  of each article as well as in the books in our list of standard references.

In connection with this question, the list of references given in the preface might be of interest too. Google Books link.
A: The following 3 volume set (translated from Russian, edited by A. V. Arhangelskii) deserves to be mentioned among references for general topology, too.
It is part of Encyclopaedia of Mathematical Sciences series.

A: Topology without tears of Sidney Morris is a great book to learn topology. It's written in a very attractive way, has a lot exercises and covers a great deal of material in general topology and some material in real analysis. It has been updated  recently and now has 12 chapters instead of 10 when is was firstly released. It has also appendices that include Hausdorff dimension, dynamical systems, set theory filters and nets and other topics. I read that it will be updated in the future and will contain 15 chapters and more appendices. You can download for free everywhere but I insist to try finding the recent updated version that I mentioned above. My personal opinion is that this book is like a bible for someone who likes general topology.
