A good bibliography should be such that the content of the Bibliography is unique and as such it is an important source of information for researchers. From a long time frame abstracts can be added to a bibliography. Also, new contributions can be included in the Bibliography. One can also urge the user to please give a note and fill a form or contact the bibliography focal point in his or her respective country.

A bibliography can be prepared by members of an Association and a joint website, combining data and the database of another Bibliography can be created by the Association in co-operation with the bibliographie classique and a Graduate Center of any City University where the project is housed.
