CALI has published a coloring book authored by three librarians, Elizabeth Gotauco, Nicole Dyszlewski, and Raquel M. Ortiz, that gives an introductory primer on how to do legal research. Along with essential information, it also provides line drawings for the reader to color in.
The PDF version of the book is free online, so you can download and print it out if you need either some coloring exercises or some basics on how to find legal information and precedents.
