Nolo books are usually the first ones I turn to when I need a reference book, but when it comes to Social Security and Medicare, the book to get is Social Security: The Inside Story, 2018 Silver Anniversary Edition by Andy Landis. Social Security, Medicare & Government Pensions is probably useful, especially if you anticipate problems with your social security or Medicare benefits, but overall nowhere near as good as Andy Landis' book. Matthews' book is confusing, the copy and paste function is abused as much of the information is repeated over and over again, and he continually gives his political views on the programs, which detracts from its usefulness. Start with Landis" book and only get this guide if you need more information or are having problems with your benefits.
