Hey guys, the Springer publishing house is releasing a lot of their ebooks for free... for reasons that I didn't care enough to learn. However, I thought you guys might be interested... there's plenty of computer science books and also for other disciplines...
I've no idea for how long has it been like this and until when it will be open, so we will find out for ourselves I reckon.
Anyway, here's a screenshot showing the website for computer science books. I just went to www.springer.com/computer
Just untick the "include preview-only content" option
