Did you give or receive a book as a gift for the holidays? Did you give or receive an e-book reader for the holidays? PBS's "Mediashift" blog reported recently that despite the ever increasing popularity of e-books and Kindles and Nooks, "Print Books Still Rule the Holidays." The article - and a poster we uncovered in our storage room last week - reminded me that one of my favorite kinds of books to give and receive as a gift is a pop-up book. (A pop-up book is truly, as the old poster stated ... a Gift you Open Again and Again.) I enjoy getting any kind of book as a gift, of course, but as space in my home becomes more limited, I like to own books that I can't borrow from the library. And pop-up books are just not transferrable to e-book format. They are works of art designed for the physical, 3-D world.
