I find the SMPS snubber application notes from Christophe Basso of ON Semiconductor, to be well written and easy to understand. So is (his book), in my opinion. Another excellent textbook is by Abraham Pressman (link).
Rudy Severns runs a website dedicated to snubber design, at ([url]www.snubberdesign.com)[/URL] and he also made an introductory YouTube video (link).
And there is also a very brief article about them on Wikipedia. The first internet search hit for "snubber" is this Wikipedia page.
Not too surprisingly, the number of RC snubbers in a SMPS is linearly proportional to the number of inductors. The constant of proportionality varies between 0.5 and 3, depending on local topology.

The following is an article written by John Camille that appeared in Sound Practices magazine issue number 7. Thanks to Joe Roberts for allowing it to be reprinted. It discusses a technique to reduce rectifier noise in high voltage power supplies. Sound Practices was an audiophile publication focused around single ended tube amps. 16 issues were published back in the early to mid 90's. The right column on the last page is the contents of the issue with the statement from the publisher allowing it to be re-published.

Mark,
You are a B##%%%%!! $300.00 worth of books I gotta buy now! In the future can you accurately recommend cheaper ones!

P.S. Thanks for the references.
John ("Buddha") Camille published those same ideas in issue 03 of VALVE magazine, 1999, in an article called "Buddhafied Afterglow". The entire publishing history of VALVE is available online as a .zip archive of .pdf files (or at least it was back on 27 Sept 2014 when I downloaded the whole shebang -- I hope this is still true). John called the circuit "RRSF" (reverse recovery spike filter) and emphasized that the series resistors should be wirewound so they will also contribute some series inductance.
Google around and see if you can find the pre-Y2K discussion.

Ed - glad you liked the book recommendations! BTW do a quick for Christophe Basso's app notes from ON Semiconductor -- they're free.
