We're on the search for a picture book for a patron that she read while growing up in the late 70s or early 80s. It is about a community of trolls (or otherwise green things) who dug and lived underground. She said it wasn't a scary book at all. She also said that when they got sad, they took a nap in the cemetary. I tried a "troll picture book" search on Google and showed her 5-6 covers but she said none of them were the book. If anyone has a clue, please send me an email off list. Thank you!
