However attractive the format, there are, as noted, some problems with this volume. One may get the impression from the introduction that the writings all stem from Muir's 1888 journey. This isn't true as most of the excerpts come from books published years later, even posthumously. No attribution is given to specific passages other than a general section label of the name of the state. So a reader interested in following up on the excerpts faces quite a chore in locating their sources.
Some excerpts are so short as to be quotations rather than excerpts.
The book may therefore be a nice gift from one lover of Muir to another, as an expression of love. Best to read the excerpts to each other aloud in front of a fire on a cold winter's night.
