The EMU Library tries to provide current computing books in electronic format.
Books24x7 is the richest source for the most current CIS eBooks, so it's often the best place to start. However, it is limited to only 3 total users at a time, so you may also wish to search eBooks from other publishers. Most eBooks can be read via your computer from home when you authenticate with your EMU NetID. Many have restrictions on printing, downloading, etc.
Remember that the library contains both print and electronic material.
