For once Amazon has alerted to something I am genuinely interested in:

As Poison Ivy can testify I am not gifted in spatial awareness and directions (still can't find her house without a map despite it being barely a mile away from where I have lived most of my life) and as a result I found Barbara Strachey's "Journeys of Frodo" a real boon when reading LOTR - particularly when the various companies diverge and I have never had a strong concept of the geography of Beleriand so I think I will break my "no more new books until I have read those I have already bought" resolution for this since I need to reread the primary works and I think this will be a great help.
Brian Sibley very kindly participated in our discussions of the BBC radio series (which we must complete sometime).
