Short book that may be of interest to some of us. http://www.morganclaypool.com/doi/abs/10.2200/S00452ED1V01Y201210WBE003

[This book is part of a series of 'lectures' designed to give an introduction to a topic, so each chapter describes what it is they are talking about, which is helpful. I took a quick look at it and it seems like fairly detailed library science/metadata material, but not excessively technical in the programming sense].
