Among other standards the newsletter contains proposed packaging standards as well as calls for comments. The newsletters are available at http://web.ansi.org/standardsaction, which lists recent newsletters that contain proposed standards that are still within the 60-day comment period. Back issues are available on-line but to ANSI members only. The newsletters are in Portable Document Format (PDF) a universal cross-platform format. Free software that can read PDF files can be downloaded from the site. Though ANSI doesn't provide the ability to comment via its Web site e-mail addresses for contacts are listed within the newsletter according to the organization.
