For the publisher, therefore, the question is which packaging best suits the needs of each individual project. Early in the development of DVD, the Video Software Dealers Association, known as VSDA, made several recommendations as to the packaging guidelines to be followed. As its name implies, this packaging opens up like a book. Some styles are molded on both sides, with room for a disc on both flaps. Most of the printed material is on the outside of the package and, if there is only one disc, on the left inside flap.
Some styles have a molded tray on the right and a paperboard flap on the left and the back.
If desired, the left flap may have several fold-out parts, allowing extensive graphics. Some snap shut, some are secured with small flaps, and other styles fit together tightly. This involves a molded tray, which is pulled out like a drawer from one end. They tend not to have as much space for graphics as the Book styles do, although one Slider type allows up to a 32-page booklet. Some are virtually indistinguishable from a CD Jewel Box, though made of a more durable material so they don't crack as easily.
