The Bond Book: Everything Investors Need to Know About Treasuries, Municipals, GNMAs, Corporates, Zeros, Bond Funds, Money Market Funds, and More Hardcover – October 27, 2010

This is a very good resource for those interested in bonds and explains the key concepts very accessibly. It is not just theory but also has practical advice such as where to get information and how to access the market. I believe you could go from no knowledge to early stages of competence just via this book.However, the subtitle should be taken seriously, it is very focused on the US market. Furthermore, in the early chapters, it outrightly says there is little point in getting into bonds (excluding treasuries) unless you have USD 100,000 or more to invest, which obviously excludes the vast majority of investors and, if you have that kind of money, you are probably more likely to simply go to a financial advisor anyway.
