As a state agency, everything the University community creates - both in hardcopy and electronically - is considered a record, regardless of physical form or characteristic. All records must  be retained according to a legally approved records retention schedule.  How long the information is retained is based on content and purpose, not format.

These records may include, but are not limited to:
  E-mail
  Snail Mail
 Research Data
  CD/DVDs
  Studies
  Drawings
  Webpages
  Audio/Video
  Maps
  Rolodexes*
  Memos
  Blog Posts
  Texts
  Calendars
  Databases
  Photos

* But it might be time to upgrade :)

The State of Washington formally defines a record in RCW 40.14.010 as -

any paper, correspondence, completed form, bound record book, photograph, film, sound recording, map drawing, machine-readable material, compact  disc  meeting current industry ISO specifications, or other document, regardless of physical form or characteristics, and including such copies thereof, that have been made by or received by any agency of the state of Washington in connection with the transaction of public business, and legislative records as described in RCW 40.14.100.   

University records are public records and may not be destroyed, transferred to the University Records Center, or transferred to the University Archives without an official retention period approved by the State Records Committee.
