This is ideal for the Kindle rather than the usual thick volume. In addition, by having this on the Kindle you can change the font size whereas the normal Wisden font in the printed version is quite small. Maybe the full version will eventually end up on the Kindle.
I've been collecting Wisdens since 1961 and have several earlier copies than that, although sadly not the complete set! The Kindle Shorter version is great to dip into (particularly now I am using a Kindle Fire)
