The American Library Association was founded in 1876 and based in Chicago, Illinois. The oldest and largest library education and promotion association in the world, they have featured the Muppets in many advertising campaigns over the years.
In 1998, a campaign featuring poster and bookmarks was launched under the title, "Building a Nation of Readers". The promotion featured Kermit, Miss Piggy and Rizzo the Rat building a house of books. 
- In the book A Visit to the Sesame Street Library, Bert and Ernie are featured in one of the many "READ" posters seen throughout the library. The poster is a reference to the 1980 poster featuring Kermit and Miss Piggy.
