Mostly I like this Book.  Leilong is a big boisterous green dino.  He just wants to go to the library for story time.  Overall this book is exactly what you expect from the title.  However, I do wonder if the author is a librarian, or bothered to talk to a librarian about policy because there are multiple times where the librarians in the story tell Leilong he can not come in because he doesn't have a card.  They don’t even offer to get them a card.  I do not know of a single public library in the US that will not let you enter the building without a card.  Usually you only need the card to walk out of the door with materials, or to download digital materials.  I have never heard of a library that makes you show your library card to attend story time.  So except for that mistake, I do like this book.
