I have a soft spot for textbooks as well.
A lot of institutions will buy licenses to them via ClinicalKey or some similar online database, and anyone with eLibrary access can be able to read them.
I prefer Kindle.
I've been eyeing the new Devita oncology textbook but too cheap to pay the 265 bucks for it.
I wish boyiadzsis would update their friggin textbook, the cookbook is getting out of date.
That said, most fellows do not need textbooks between ASCO SEP and ASH SAP, which are as good as any textbook. Pocket Onc is a nice road map, not meant for deep understanding of a topic, but allows you to get a 30,000 foot view of most of the diseases you'll see.
