Colophon

The animal on the cover of Oracle SQL*Plus: The Definitive Guide is a moving leaf (Phyllium giganteum), a large (about 10 cm in length) Malaysian leaf insect related to stick insects; together these constitute the order Phasmalida,

derived from the Greek word for ghost These stunning insects imitate local foliage with intricate detail, down to the leaf-like veins on their legs and tattered brown edges to mimic dead leaves Moving leaf insects feed on bramble and other plant material Kept by many entymologists as exotic pets, they require high temperature and humidity

Ellie Fountain Maden was the production editor and project manager for Oracle SQL*Plus: The Definitive Guide, and

also copyedited the book Quality assurance was provided by Madeleine Newell, Sarah Jane Shangraw, and Sheryl Avruch, who was also the production manager Ellie Cutler proofread the book, and Seth Maislin wrote the index
