Here's a key to the markup: [page-number]: serious technical mistake {page-number}: minor technical mistake : important language/formatting problem (page-number): language change or minor formatting problem ?page-number?: reader question or request for clarification This page was updated March 8, 2007. UNCONFIRMED errors and comments from readers: (v) I'm not sure if the chapter "number" for the first chapter is a typo or simply a poor font choice, as it appears to be the numeral zero followed by the capital letter I "eye". The same text appears on page 2, simply at a larger point size, so at least the choice is consistent. Finally, I'm not sure why the typesetter chose the cutesy style of inconsistent use of the baseline for the numerals in the chapter numbers; chapters 1, 2, 6 and 8 use the same baseline for the pertinent digit as 0, while for chapters 3, 4, 5, 7 and 9 the pertinent digit has a lower baseline. In a book that is about effective interface design, I find this an amusing choice to encounter on practically the very first page of the book. (26) 3rd paragraph of the page & caption of Figure 2-4 on the same page; There is minor mistake in the third paragraph: "The iTunes music store organizes its thousands of songs by album, artist and then genre..." In fact, a genre is selected first. The text should read, "The iTunes music store organizes its thousands of songs by genre, artist and then album..." The mistake is repeated in the caption in Figure 2-4: "The iTunes Music Store categorizes songs by album, artist and then genre."
