Email and Personal Information Manager (PIM) formats which includes functionality for instant messaging, contacts, calendars, tasks, appointments and other personal data are often bundled together in software packages or related applications.

Inclusion of a format does not imply that it is preferred or acceptable for Library of Congress collections. Conversely, omission of a format from the list does not imply that it is not preferred or acceptable. See the Recommended Formats Statement for more information.
