Non Fiction

1. True Crime is primarily in 364 although some is in biography as well. I would recommend Erik Larson's Devil in the White City (364.1523L) or Ann Rule's newest edition of Stranger Beside Me (364.1523 R)

2. The classification of non-fiction travel narrative depends on the country or countries visited.  Paul Theroux's Dark Star Safari (916.04 T) is classified in African travel while Tahir Shah's Caliph's House is classified in 964 D, the history and culture of Morocco.

3. Biography can be included in the Bio section, History , Sports, Business -- that classification for which the subject is noted. Thus John Krakauer's Into the Wild, bio of doomed Alaskan adventurer Chris McCandless in Bio Mcc and President in the Family about Thomas Jefferson by Woodson in 973.46 W.

4. Disaster Narratives -- classified depending on what kind of disaster it is. -- if it is about mountain climbing such as Krakauer's Into the Thin Air, 796.522 K, or The Graves are Walking by Kelly (941.5081 K) classified in the history and culture of Ireland - about the Irish Holocaust- or Enron, the  Smartest Guys in the Room (333.79M) by McLean, in the business and finance section.
