Ever want unlimited access to books at the click of a mouse? Yes there is Google’s effort to catalogue everything (Google Books ) but it has been met with much resistance. On the other hand the team at safaribooksonline.com  has done a better job in the computing and business area. I wont go through all the details of what is offered as their website does a better job.
As for pricing it is not free. The subscription (as of 31 Aug 2009) is USD $22.99 per month or USD $252.99 per year for the 10-slot Safari Bookshelf version. This means every month you can fill your 10-slots with any book and browse it freely, some books take more than one slot.
If you like something more complete then look at the Safari Library version that costs USD $42.99 Per Month or USD $472.89 Per Year and you have unlimited access to any book you wish and sneak peaks and commenting abilities of books still in production (rough cuts). You also get 5 complimentary tokens per month which you can use to download chapters or whole books on offer.
Recently the IEEE Computer Society has introduced the 10-slot Safari Bookshelf version with their membership, besides the other great benefits of being a IEEE member. I think this really adds value to the IEEE Computer Society and is a great idea. As for the price see the dues for IEEE membership and IEEE Computer Society on the IEEE site .
As an example a student for a full year (as of 31 Aug. 2009) you will pay $27.00 per year for IEEE memebrship and USD $25.00 per year for IEEE Computer Society with access to safaribooksonline.com
Did I mention the free search facility?
I would like to make it clear that I have not been sponsored by safaribooksonline.com in anyway. It is just such a good resource to use in research, literature reviews and everyday computing. I hope it doesn’t make libraries obsolete!
