He Went to the Library

Another librarian put together this book display with library themed romances. Be as broad as possible when setting up this sort of display. If a book has a librarian in it or library scene, it is enough. Romance is a genre rich with tropes so you can assemble a display that fits your collection or those titles that need some patron attention. 
Alter the text on the sign and a quick and easy cozy mystery display could be put up with the same theme.
