CEIPP

The C.E.I.P.P., or the "Centre "(formerly "Cercle")" d'Etudes sur l'île de Pâques et la Polynésie" ("Study Centre (formerly "Circle") on Easter Island and Polynesia") is a geographic and anthropological group created by André Valenta and Michel-Alain Jumeau.

The CEIPP is notable for its members' publications on Easter Island, which include:
*"Nouveau Regard sur l'île de Pâques," a collective work published by Moana Editions, Saintry-sur-Seine, 1982.
*"Les Mystères Résolus de l'île de Pâques," a collective work published by Editions Step, Evry, 1993. ISBN 2-9508078-0-1.
*Michel-Alain Jumeau and Yves Pioger's "Bibliographie de l'île de Pâques." Publications de la Société des Océanistes, nº46, Musée de l'Homme, Paris, 1997. ISBN 2-85430-004-1.

It also houses the Thomas Barthel archives of rongorongo, making the data available in digitized format, cross-checking his line drawings of the rongorongo corpus with available photographs and the rubbings he used, and expanding his list of glyphs and his glyph-referencing system.
