Generally, new versions of translations already published were not undertaken and it was rare for a little-known contemporary author with only a small output to his name to be considered for inclusion.
Member States suggested lists of works which they consider to be representative of the values of their cultures.
Internationally recognized cultural organizations, such as the PEN federation of writers and the International Council for Philosophy and Humanistic Studies were also called upon for advice in the establishment of the lists.
In addition, suggestions were received from publishers who were willing to undertake the translation of particular works which they consider worthy of a place in the Collection.
The UNESCO Digital Library (UNESDOC) provides information about works published under the project, as well as associated documents.
