Reading Levels
These are general guidelines which overlap significantly. 
Buyers: when searching or browsing, choose all that may apply and then narrow your results if necessary.
Sellers: use the most appropriate level that will help buyers - don't use All Ages except for very special items.

Babies to Beginning Readers - basic words and concepts and a limited, beginning vocabulary -  very large typeface - text usually consists of single words and phrases or very simple sentences often designed to be read to the child - always illustrated - usually fewer than 24 pages.

Early Readers - most are divided into chapters (chapter books), but not all - usually a large type face (14 pt) -  varied but uncomplicated vocabulary, simple plot development and non-controversial themes - typically has many illustrations, but with at least a paragraph on each text page -  usually from 30 to 180 pages, but sometimes more.
Middle Readers - easy-to-read type face (12 -14 pt) - titled chapters - some illustrations (often on the chapter title pages) - broading vocabulary and maturing themes often with plot twists and surprise endings - typically has between 150 to 250 pages, but can be more or less.
Young Adult - similar format as regular adult novels: regular type face (12 pt) - few or no illustrations - mature vocabulary - complex plot development and well developed characters - can have controversial content and themes - usually has fewer pages than adult books, often 200 to 300 pages, but can be more or less.
This reading level category is for the books listed on our site that are not designed for children, but for teachers, parents and others.  This option can also be used for some classics and modern Adult fiction that is popular in high school libraries (Shakespeare, Stephen King, etc.).
All Ages Items that are written for all readers regardless of age.  Seller Note: Buyers can exclude this value in their search or browse requests, so be sure you want to choose this value over a more specific reading level that buyers may be seeking.
