I will pass on to all that will listen what a fantastic publication an O'Reilly book is. Thanks for your kind words. We, too, are sorry that you didn't discover O'Reilly sooner, and we're glad that you're now making up for lost time. Thanks also for not lending others your O'Reilly books. Let others buy them.
Buyers respect their books.
In the last few months, I've had to struggle with some quality complaints from other voracious O'Reilly readers. We're working to address those quality complaints. It's very nice to get email telling us how useful our books have been, especially when that email comes from a system administrator, the Atlases of the network. We can judge the quality of an O'Reilly book by seeing if the systems managed by its readers are running efficiently and constantly.
