I've had the 1974 first printing for 35 years from Howard W. Sams and I confirm that the objectionable bold-print problem reported by George Wang et. al., existed then, though his page 12 was then page 20, figure 1.9 then on page 24 is a little blurry but quite legible and my copy has 15-pages on active-filters in two-sections, someone mentioned that the third-edition has none (?). In 1974 my copy included 591 pages for $12.95 at Pioneer-Standard Electronics in Akron, OH. It appears "to me" that perhaps Howard W. Sams & Co., inc. sold the "defective" master-plates or whatever to Prentice Hall with no changes in 35-years. There is nothing in the First Printing that I cannot read but I have had a lot of practice. I was reading the reviews to help me decide if I "need" a copy of the third edition ... I still don't know what the third edition has that the first-printing does not. It is always an educational experience ... somehow.
