I’m not familiar with any books on growing just pumpkins, but a quick search online does list a few on growing pumpkins in general, or the huge record-breaking kind. For example, “The Perfect Pumpkin: Growing/Cooking/Carving” by Gail Damerow (1997) and “Gardener’s Guide to the Pumpkin and Winter Squash” by Paul R. Wonning (2016). Hope this helps!
