IEEE Computer Society Digital Library
File this under underutilized.
The IEEE Computer Society Digital Library provides online access to 22 society magazines, transactions, and letters, as well as a growing collection of conference proceedings and workshops. Most of the magazines, transactions, and letters go back to 1988, or to volume 1 for publications that began after 1988. The IEEE Computer Society Digital Library is great place to find items on the practical aspects of computing, and theoretical and experimental peer-reviewed articles.
