We give a size restriction on the Khovanov homology of almost alternating links. We relate the Khovanov homology of the connected sum of a link diagram and the Hopf link with the Khovanov homology of the diagram via a short exact sequence of homology which splits. Finally we show that our results can be adapted to reduced Khovanov homology and we show that there is a long exact sequence connecting reduced Khovanov homology with unreduced homology.33 pages, 26 figures, to appear in Proceedings of the Workshop, ``New Techniques in Topological Quantum Field Theory" Calgary/Kananaskis, Canada, August 2001; Ed.
