Any books or resources which talk about writing MMORPG servers?

I'm writing an MMORPG server, and I can't seem to find any resources about this. Can anyone suggest me a good book or websites which about this subject?Any books or resources which talk about writing MMORPG servers?
Well,

first, you MUST know how a basic server works. If you don't want to spend days or weeks reading huge articles about that, you could easily understand that just by learning network programming.

Doing so, you will learn how a server and a client communicates between themselves and then, will be able to project your MMORPG server.



But that is not enough. A MMORPG server does not work exactly as a web server (for instance). There are A LOT of different concepts to review.



I PERSONALLY do NOT recommend a single book for you to learn it.

I'm also learning that, and for me it's MUCH better to read different articles on the net about this topic, because by that way you will be able to realize the difference between their point of view, and that really helps when learning something by yourself.

great makeup
