Virtual Extension
As with all magazines, page limitations often
prevent the publication of articles that might
otherwise be included in the print edition.
To ensure timely publication, ACM created
Communications’ Virtual Extension (VE).
VE articles undergo the same rigorous review
process as those in the print edition and are
accepted for publication on their merit. These
articles are now available to ACM members in the
Digital Library.
