How long will that hardcover last?

It's probably safe to say that most people expect hardcover books to last for decades. But cost-cutting at some publishers is reducing the life of the paper in many hardcovers to just a few years.
Publishers can save about 10 cents per book (wow!) by printing on de-acidified groundwood paper rather than freesheet paper. Groundwood is pulped by a mechanical grinding process that leaves lignin in the paper, and lignin rapidly yellows paper. Freesheet paper is pulped by a chemical process that removes the lignin.
Historically, hardcover books have been printed on freesheet, while newspapers and some paperbacks (especially mass-market) have been printed on groundwood. Over the past decade, however, some of the publishers have started using groundwood even for hardcovers. A 2005 report (link is PDF) points to Penguin, Simon & Schuster, and Warner (now Hachette) as groundwood users, while HarperCollins and Random House were standing firm on freesheet except for R-H's Value publishing division. According to Permanence Matters, half of the New York Times bestseller list is printed on groundwood (I imagine this is a "typical" number, not tied to a specific week).
The report linked above passes along some rumors that some groundwood publishers print library copies on freesheet, and that some freesheet publishers print books destined for Walmart and the like on groundwood.
Unfortunately, it seems that it's difficult to impossible for the book-buyer to distinguish the two kinds of paper. [The following information is just from some quick research; I haven't tried it myself.] Groundwood tends to be less white, but that's probably easily covered up by bleaching. And at least until recently, freesheet paper for books was left an off-white rather than being bleached to pure white. Groundwood has a very slightly smoother feel to it. Groundwood weighs less, by maybe 10-20%, than freesheet.
