The treatment of bibliographic information in library catalogues is biased by the primacy of printed written resources. This legitimate bias hinders oral tradition resources from being accurately described and accessed. This kind of resources is important in any society, but central in indigenous societies, at least for the comprehension of the printed written resources of these societies. The FRBR Model allows a better treatment of oral tradition works, versions and items. It can express the essential fact that oral traditions works are independent even when their manifestations are not, collective and not anonymous, plural but not impossible to grasp. One deep doubt remains concerning the compatibility of the FRBR notion of expression and the notion of version.
