Paper copies of the Recyclopedia are available at Madison Public Libraries and can be mailed to your home by request (just contact the Streets Division).
The new Recyclopedia is designed to be easy to use and search while on your computer. You're welcome to download the PDF file or just bookmark the page. Be sure to update your bookmarks with the 2019 version.
And for something that has more detail than the photo guide, but less than the Recyclopedia, here's our reference guide to the rules and guidelines for recycling.
