The U.S. Army released 33 pages of Bruce Ivins' e-mails Thursday from his account at Fort Detrick.
The e-mails, obtained by The Frederick News-Post under the Federal Freedom of Information Act, span the period from September 1998 through January 2002.
The documents contain 16 threads of communication, some including multiple e-mails between Ivins and his correspondents.
The e-mails all address one of three issues: the work of Ivins and other individuals to plan an international meeting of anthrax researchers in Annapolis for the summer of 2001; discussions of lab research; and in two cases, copies of The New York Times articles about the investigation into the 2001 anthrax mailings that Ivins e-mailed to himself.
The news articles both concern the difficulty investigators had early on in tracking the history and origins of the Ames strain of anthrax used in the mailings.
The Army continues to review additional e-mail messages from Ivins.
In August, the Department of Justice announced it considered Ivins, a U.S. Army Medical Research Institute of Infectious Diseases microbiologist, its sole suspect in the 2001 anthrax mailings that killed five and hospitalized 17 others.
Ivins died on July 27 after intentionally overdosing on acetaminophen.
His attorney has maintained Ivins was innocent.
