This monograph introduces to the reader the idea of interference alignment, traces its origins, reviews a variety of interference alignment schemes, summarizes the diverse settings where the idea of interference alignment is applicable and highlights the common principles that cut across these diverse applications.  The focus is on theoretical aspects.

Work in Progress
Starting from the Foundations and Trends monograph:

Syed A. Jafar, ``Interference Alignment: A New Look at Signal Dimensions in a Communication Network'', Foundations and Trends in Communications and Information Theory, Vol. 7, No. 1, pages: 1-136. http://dx.doi.org/10.1561/010000047

the goal is to update the material frequently (as often as time permits) to stay current with new developments on interference alignment.
