This is my understanding.
oj meaning "Ojibwe" really describes Anishinaabemowin, an Algonquian dialect continuum that spans from Quebec to British Columbia in Canada and Michigan to Montana in the United States. How that dialect continuum gets divided and what gets included as part of that dialect continuum is up to much debate. Some include pot (Potawatomi) and alq (Algonquin) in that dialect continuum while others do not. But generally within that dialect continuum, the prominently recognized dialects that are mutally intelligible among neighboring dialects but that intelligibility diminishes farther apart they are includes otw (Ottawa or Southeastern Anishinaabemowin), ciw (Chippewa or Southwestern Anishinaabemowin), ojs (Severn Ojibwa, Oji-Cree or Northern Anishinaabemowin), ojg (Mississauga Ojibwa or Eastern Anishinaabemowin), ojc (Central Ojibwa, or more accurately Central Anishinaabemowin consisting of Nipissing Ojibwa and North of Superior Ojibwe, two very distinct dialects lumped together), ojb (Ojibwa, or Northwestern Anishinaabemowin, and ojw (Saulteaux or Western Anishinaabemowin), with no dialect codes for transitional dialects such as Berens River Ojibwe, Border Lakes Ojibwa, and Island Lake Oji-Cree.

I am the one whom StruthiousBandersnatch was referred to by the Mille Lacs Band of Ojibwe media content coordinator.
Just to note, ''Ojibwe Inaajimowin'' title is in Anishinaabemowin more specifically in "Chippewa" but the contents of this monthly newspaper is primarily in English, and usually only one page per publication issue is devoted to Anishinaabemowin.
