SearchEngineWatch has an article this week, "Going Under Cover With Books Search Tools" — about accessing books online with Google Print — in which I think the author gets one or two things wrong.

The "Here's how" section suggests narrowing a search to Google Print material by inserting the word "books" before your Google search words or phrase. Inserting the singular "book" is the preferred method, however; "book" works just as well, and saves typing dozens of extra Ss. That's what you do when you're scouring a resource: you type endless combinations of keywords and phrases in quotes into the search box.

To get to a Google Print search box, the article suggests picking one of the displayed results, and then scrolling to the bottom of the first page where the search box appears. Far better than doing all that scrolling, Google displays a "Book results for..." link, right at the top of your original search (with "book") result, which links right to all the Google Print results — with excerpts — and a Print-only search at the top. No need to cut through the backyard of a (possibly) useless result.

The article does have a good list of "[a] few things to keep in mind" when searching Google Print, and I love the quick and dirty "Add your search terms to this URL":

I also discovered today that Google Print has a Recursive Book Factor of eight (RBF8):

book

"book book"

"book book book"

"book book book book"

...

"book book book book book book book book"
