mechanics, physics and astronomy, as chemistry had now its own publication, Série IIC. In 2000, Série IIB became dedicated exclusively to mechanics, whereas astronomy was redefined as astrophysics and, along with physics, was now being covered by the new Série IV. The latter began publishing in March, however Séries IIB published two more issues, in April and May, still containing material on physics and astrophysics, before starting a new run (under the same title) also in May dedicated solely to mechanics. 2002 onwards The present naming and subject assignment was established in 2002: Comptes Rendus Biologies – life sciences except paleontology and evolutionary biology. Continues in part Series IIC (biochemistry) and III. Comptes Rendus Chimie – chemistry. Continues in part Series IIC. Comptes Rendus Géoscience – geosciences. Continues in part Series IIA. Comptes Rendus Mathématique – mathematics. Continues Series I. Comptes Rendus Mécanique – mechanics. Continues Series IIB. Comptes Rendus Palévol – paleontology and evolutionary biology. Continues in part Series IIA and III. Comptes Rendus Physique – topical issues in physics (mainly optics, astrophysics and particle physics). Continues Series IV. Online open archives The entirety of Comptes rendus de l'Académie des Sciences publications from its start in 1835 all the way to 1996 have been scanned and undergone character recognition, and are available at the site of the France National Library as part of its free online library and archive of other historical documents and works of art, Gallica. Besides occasional flaws in the character recognition which might hinder text searches, it's worth pointing out that the files of Comptes rendus de l'Académie des Sciences archives are strewn about the site in a quite disorganized manner. Some volumes are presented as one year's worth of collected material, some as individual issues, and some issues are grouped together for no particular reason. Some parts are broken up by each study instead of issue or volume, some parts are incorrectly tagged, occasionally some issues will be filed as having come before later ones, and so on. Yet it seems that the entire back archives of these publications are indeed present, so researchers unaware of this might miss valuable information. It would be a good idea to see all of a year's releases at the same time—in the "Issue by Date" tab, below the month's calendar, there's a link for that. The links presented here seem to cover the entire available archive of
