Logology 2: another soon to be classic logo design book that had slipped me by, but one I shall not be without given the utter nightmare of trying to get hold of the ultra hard to find orginal Logology.
I ended up finding some obscure online shope somewhere in Antartica that had one copy of the first edition of Logology to hand, and if you are able to find a copy it is certainly worth paying a premium for just for the embossed leather cover itself.
Seems it came out in 2011 and already Amazon are not selling this direct which leads me to believe it will also soon become hard to come by, so certainly worth getting your copy now. There are a couple of sellers selling it for around £35 plus P&P.
