"If you're an oldies fan, collector, broadcaster or retailer, OLDIES ON CD by Mike Callahan is one reference book you simply must have. With more than 10,000 titles listed, OLDIES ON CD is the most accurate and authoritative resource available. Just buy it!" -- DICK BARTLEY (American Gold/Rock & Roll's Greatest Hits/ABC Radio Networks)

"Quality CD sources are a must in my business. To locate these sources quickly, including information on mono/stereo and sound quality, I depend on Mike Callahan's OLDIES ON CD. A must for music business pros and hobbyists alike." -- BUD BUSCHARDT (Freelance musicologist/ABC Radio Satellite Network/TM Century - Gold Disc)

"Some of the CD companies that used to be good are getting bad, and some of the bad companies are getting good. Who has time to keep track of it all? Mike does! It's all here!" -- WALTER DeVENNE (Reissue Producer/Radio Personality, WODS (CBS) Boston, OLDIES 103-FM)

"Absolutely indispensable. The Bible of CD sources." -- STEVE GODDARD (KPSN Phoenix/Host of Goddard's Gold)

"There is no other publication or reference guide to compact disc 'oldies' that is as detailed and comprehensive as Mike Callahan's work... obviously, an absolute labor of love. Unlike most other reviewers and editors, Mike understands the nuances of both good and bad mastering, and puts his knowledge (and opinions!) to use within the reviews themselves. As an added little bonus, readers' comments are occasionally included; they're sometimes dead on, at other times a real hoot." -- BOB IRWIN (Producer, Sundazed/Sony-Legacy)

"I rely on Mike Callahan's publications to be sure that only the best stereo versions available of the hits are programmed on Unistar's Oldies Channel, and our shows, including Solid Gold Saturday Night, Country Gold Saturday Night, Super Gold, and Dick Clark's Rock Roll and Remember." -- ED SALAMON (President, UNISTAR Radio Networks)

"While most reviewers only review the contents of new CDs, OLDIES ON CD lets you know what the sonics are like. As there is a wide variance these days in the world of reissues, OLDIES ON CD can be of great help in deciding which version of your old favorites to buy." -- BILLY VERA (Recording Artist/Reissue Producer/Author)
