The studies reported in this volume of Written Language and Literacy all derive from a joint project entitled “Developing literacy in different contexts and in different languages”, funded by the Spencer Foundation, Chicago. The study encompasses seven languages — Dutch, English, French, Hebrew, Icelandic, Spanish, and Swedish — for which data were collected in Europe, Israel, and the US by graduate research assistants in education, linguistics, and psychology, under the supervision of a project director in each country — each of whom is listed as a first or “lead” author in the articles which follow the introduction to this collection.
