Did you know that you can get excerpts from books and other material otherwise not online by searching on Google Print?
You can search using this feature of Google by adding the following bit to your search query: site:print.google.com.
This query yields a list of resources with all sorts of excerpts from books that talk about chocolate mousse, including some full recipes.
It’s unclear how copyright owners are/will be reacting to this. You would think as long as the excerpt is just an excerpt and the page includes a link to online book retailers where users can then purchase the book they would embrace it. It may be a bit more complicated with magazines as copies of those for sale are usually not just a click away.
