I have added mentioning of the model of EM-spaces $K(A,n)$ as the “reduced A-linearization of the $n$-sphere” $A[S^n]_\ast$ (for countable $A$, at least), here.

(That’s the model of EM-spaces which lends itself to the definition of the EM-spectrum as an orthogonal spectrum)

]]>Added to *Eilenberg-MacLane space* a section *Cohomology – Of EM spaces* with a minimum of pointers and the statement of the rational cohomology ring of $K(\mathbb{Z},n)$.
