This guide is from the Which? organisation who are well-known for providing straightforward and honest advice and recommendations about all sorts of consumer goods and services. Here they have produced a book as a guide to Excel 2010, which is full of examples, easy to follow, clear text, and lots and lots of useful screenshots. I find these images really helpful and important in a book like this because I can refer to them to confirm that what I should have on the screen in front of me after following the written instructions looks the same as what they show in the book, and thereby know that I am working along the right lines. There are plenty of full colour screenshots; I think there's one or more on virtually every page.
The book is organised into logical sections, beginning with getting started and the basics of opening and saving a workbook. Then it moves on to worksheets and cells, formulas and functions, photos and graphics, and viewing and analysing date. There's also a section on keyboard shortcuts, a `jargon buster', and a decent index.
I think this is a very accessible book with clear text and helpful images, and is an ideal starting point for teaching yourself about Excel. It should be particularly useful for anyone who is totally new to using the Excel software and also for people who can use it a little but would like to learn a bit more and improve their skills. I imagine that there are much more advanced things that can be done with the software which may not be covered here, but this is certainly a useful introduction or refresher.
