Witte Boekje

Witte Boekje (English: White Booklet) is the popular name for the Spelling Guide of Our Language (Spellingwijzer Onze Taal), a publication of the Genootschap Onze Taal. The first edition was released in October 1998; the latest edition is the tenth and was released in 2004. All these publications are explanations of the official spelling rules, as set by the Dutch Language Union.

Although the words in the guide have been based on the same official rules as the Green Booklet, the spellings in the two booklets do not always match. To aid users, the differences between the White Booklet and Green Booklet are made clear by appending GB to the differently spelled words.
