Introduction
The Association for Computing Machinery (ACM) is a not-for-profit organization that was established in 1947 and is the oldest and largest computing society (Mandelbaum 2005; About ACM 2007). In July of 1997 the ACM's Digital Library (DL) first became available allowing users to access ACM publications, with full-text accessibility back to 1991 (Denning 1997). Today the ACM DL and The Guide (The Guide to Computing Literature) have over one million records within their holdings (Ascribe Inc. 2007). Alone, the ACM DL has almost 200,000 records covering computer and information technology for individuals, researchers, businesses and academic institutions. The DL includes full-text access to conference proceedings, magazines, newsletters, and journals, covering topics in: computer technology, online education, software engineering, programming, networking, human-computer interaction, artificial intelligence, and information systems, to name a few. The ACM DL is made up of all past and current ACM publications in full-text, going all the way back to volume 1, issue 1. Through the ACM Portal subscribers can access the ACM DL and The Guide. Browsing the list of publications can provide a better overview of what the ACM DL has to offer. The Guide provides users with a bibliographic database of over 3,000 publications across the entire computing field. Works indexed include books, journal articles, conference proceedings, dissertations, masters' theses and technical reports. The Digital Library and The Guide can be found at ACM Portal.
