A nice reference addition...
for any bookshelf, especially where space is limited.
I have the 1920 edition, which is not a first edition (seems to be the 1915 edition). It is small, compact, and sufficient for quick reference (for more detailed analysis, I use Thayer's).
The spine of my book suffers the standard UV damage, though still easily read, and the top of the spine is worn, suggesting it was pulled off the shelf frequently by its owner(s).
A nice prize for my Greek NT collection...
