The ability to navigate from one page or chart to another is absolutely essential and this kindle edition is, I'm sad to say, a big fail :-(
Combined with the fact that each chart is a non searchable poor quality image just adds to the frustration. When you enlarge a chart it actually becomes less legible and the jpeg artefacts show up making it difficult to work out if there is a line through a star indicating that it's a double.
The 'Look Inside' feature actually shows the poor graphics in fairness but I naturally assumed that when I handed over my cash a lovely clear representation of the printed version would be on view, but alas, no ... just so lodges and blurs.
This is how the navigation goes:
You find an object in the index, it gives you the Chart number, but without coordinates as to where on the chart to find it and not even a direct link to the chart. You are instead expected to battle with a meaningless 'location' at the bottom of the page in the Kindle info and guess which page that location is going to take you ... eh? What's all that about?
When is this actually going to reach the digital age? I am seriously not impressed. This kindle edition is a complete let down with regards to the effort put into the publication itself.
The Kindle edition is way over priced at £6 plus, and because of the lack of coordinate references I suspect I will be saving money on the printed version.
My advice: save your money!
