You should get the book – and you can, from here. But a lot of it is available free, for example in articles. Here’s a round-up.
Section 1: What you need to know
The above are all available in the Kindle preview. Make sure to scroll to the start: it opens part-way through.
The rest of Section 1 is only in the book: covering theories of change, and the defining feature of the charity world.
Section 2: What you need to do
Ch 6. Finding a great charity. This is partly covered here in Money Week,
Ch 7. Dealing with common situations, and myths: whether to sponsor somebody in the marathon is covered here, and supporting Sport Relief (=Comic Relief) here.
Ch 9. Using money without giving it: you’ll have to read the book!
Section 3: What to do if you’re giving a lot
For most of this – how & why to decide a focus, the range of tools available, partnering, getting a good process and tracking your own impact – you’ll need the book. Article here on the wastage which foundations create by having bad processes.
Section 4: Advanced theory
Ch 17 & 18: Size, growth & mergers; Charities and government: material is in the book.
Ch 19: Principles of good giving: outlined here, in Alliance magazine.
Appendices are in the book. But all the calculations are here, as is the application form I suggest.
