After the release of the fourth book, the world of Harry Potter expanded quite dramatically. Rowling sold the film rights of the series to Warner Bros. and also signed merchandising contracts with a number of companies. Rowling was called upon to create some "filler" for the development of the video games and other products. One result of this was the Famous Wizard cards. These cards appeared in the Electronic Arts games and were included in actual Chocolate Frog candy.
The companies who used this information were not allowed by their contracts to indicate that their products included new Harry Potter information, so it can be a bit difficult to determine what is canon in, for example, a video game. However, Rowling announced on her website that she wrote the "original chocolate frog cards," so we can say with certainty that those facts are canon.
Since all of this material was created by Rowling, the Lexicon includes it. However, numerous inconsistencies can be found in these sources, some of which are impossible to rectify. As Rowling makes corrections to the text and adds details on her website, some of these inconsistencies will be ironed out. The Lexicon will attempt to include the latest and most accurate information available.
As products were developed by these various companies, it became necessary to standardize the "vision" of the characters and settings of the Harry Potter universe. The resulting artwork appeared in a variety of places, from product packaging to coloring books. Rowling didn't create that artwork, so it is not canon. The same is true for the illustrations in the Scholastic versions of the book or the cover art for any other version: since they didn't come from Rowling herself, they are not canon. Rowling did create some illustrations for the books. Some of these illustrations appear on her website while others were shown during the "Harry Potter and Me" television special. Because they are directly from Rowling, they are considered to be canon, although they include details never mentioned in the books, such as a goatee on Professor Snape.

Information from the filmed version of a book is referred to by adding /f to the abbreviation. Therefore the filmed version of Harry Potter and the Chamber of Secrets is noted as CS/f. Such information is not considered to be canon or official unless it is clear that it originated with JKR herself. Some of the details are mentioned in the Lexicon in the interest of completeness, however.
Information from the video game version of a book is referred to by adding /g to the abbreviation. Therefore the video game version of Harry Potter and the Chamber of Secrets is noted as CS/g. Such information is not considered to be canon or official unless it is clear that it originated with JKR herself. Some of the details are mentioned in the Lexicon in the interest of completeness, however.

This database has been used to supply more information about various mundane plants.
Much of the speculative material, in the form of essays and some notes, is from fans who frequent the Harry Potter for Grown Ups group on Yahoo. The fan art is by a variety of talented artists, all of whom are listed on the pages on which their work appears. They are also listed on the About the Artists page.
The maps, which are actually fan art as well, were drawn mostly by Steve Vander Ark. A few were contributed by others, and these are carefully credited like any other fan art. Each map is carefully researched, and whenever possible, references from the canon are included below the map.
