Anne of Green Gables was originally published in 1908. In addition to remaining available prints from various publishers, it is also posted on Project Gutenberg, a volunteer-driven website that provides access to over 30,000 book that are no longer under copyright. This version including the cover design was created by Jessica Madden in 2016.

Anne is described as bright and quick, eager to please, talkative, and extremely imaginative. She has a pale face with freckles and usually braids her red hair. When asked her name, Anne asks Marilla to call her Cordelia, which Marilla refuses; Anne then insists that if she is to be called Anne, it must be spelled with an e, as that spelling is "so much more distinguished." Marilla at first says the girl must return to the orphanage, but after a few days she decides to let her stay. Marilla feels that she could be a good influence on the girl and had also overheard that another disagreeable woman in town might take Anne in instead. As a child of imagination, Anne takes much joy in life and adapts quickly, thriving in the close-knit farming village. Her talkativeness initially drives the prim, duty-driven Marilla to distraction, although Matthew falls for her charm immediately. Anne says that they are "kindred spirits." The book recounts Anne's adventures in making a home: the country school where she quickly excels in her studies; her friendship with Diana Barry (her best or "bosom friend" as Anne fondly calls her); her budding literary ambitions; and her rivalry with classmate Gilbert Blythe, who teases her about her red hair. For that he earns her instant hatred, although he apologizes many times. As time passes, Anne realizes she no longer hates Gilbert but cannot bring herself to admit it. However, by the end of the book they become friends. The book also follows Anne's adventures in quiet, old-fashioned Avonlea.
