I have a subscription to the whole library, which I find incredibly useful. Are there any similar products out there with as comprehensive a library? I think I'm paying about $40/month and I'm happy with the service, but if there are any cheaper alternatives out there, I'd like to take a look. Thanks.
I have the Basic Starter - 5 slots Bookshelf, USD $109.99 per year... and its worth every penny.
I also have the full library and yes it is expensive, but as dragthor says, it's worth every penny. As for cheaper, if you are an ACM member, and you get the digital library, it includes some safari access as well. But you may find moving from the full library to the bookshelf version very, um, hampering.
There's not really anything comparable. I've taken copious notes for myself, request books from the library and actually shelled out money for O'Reilly books that I think are worthwhile, but there's not really a comparable replacement that I know of.
You could try canceling for a month and see how often you wish you had it. If you have time you can find most of the information elsewhere. Fundamentally though, you should think about the value of your time and how much time you spend looking for things on the Internet and using the O'Reilly service.
lynda.com is a good resource to have, although obviously it's video-centric.
I don't think it has nearly as many books but they are adding new ones quickly and it's much cheaper then Safari Books Online. Also you have unlimited downloads on pdf's where as Safari Books Online is 5 a month I believe?
