Query: Terrible book on runes

Mr. Blum's book was good for one thing, bringing runes back into mainstream popularity. Unfortunetly, everything he writes lacks historical accuracy. His approach to the runes stems from a psychological view, as are his meanings. He has a tendency to use different names for the runes without any consistency.His creation of the blank rune even further shows his lack of historical accuracy, and shoddy research.There are so many books on runes that are muc better than anything made by Blum.
