The Rieekan Historical Collection was an archive of documents kept and maintained by Carlist Rieekan. Among the documents collected in the archive were logs written by Jonox Forb and Vyn Rolado during their time on the planet Hoth. During the reign of the New Republic, Rieekan allowed historians to inspect and reprint documents relating to the Alliance to Restore the Republic's presence on Hoth.
