In times of economic stress, it is good to know the basics of personal finance.

Many people turn to books for help, so we decided to go back and review three of the most popular finance books of the last 15 years: Suze Orman’s “The Nine Steps to Financial Freedom” (Currency, $16.99); Dave Ramsey’s “The Total Money Makeover” (Nelson Books, $26.99); and Robert T. Kiyosaki’s “Rich Dad, Poor Dad” (Plata Publishing, $8.99).

They all have something worthwhile to offer, but after rereading them, I found that all had a glaring omission: a lack of substantive advice on investing. You will have to go elsewhere for an in-depth discussion of how to set up a portfolio and choose among stocks, bonds, exchange-traded funds or mutual funds.

What all three books do emphasize is the need to buttress your finances by doing such things as reducing debt and expenses. And they share a constant refrain: You are ultimately responsible for your own financial success.

The authors have different takes on how to succeed, though. Ms. Orman says trust your instincts. Mr. Ramsey says relentlessly eliminate every last shred of debt. And Mr. Kiyosaki says emulate the rich, who have figured out how to “have money work for them.”
