It also says that it is "indexed, linked, and inter-operable" with GeoRef. Right now, GSW is offering the content of the journals published by the founding member organizations: American Association of Petroleum Geologists (AAPG), American Geological Institute (AGI), Geological Society of America (GSA), The Geological Society of London (GSL), Mineralogical Society of America (MSA), Society for Sedimentary Geology (SEPM), and Society of Exploration Geophysicists (SEG).
"GeoScienceWorld (GSW) is a nonprofit corporation formed by a group of leading geoscientific organizations for the purpose of making geoscience research and related information easily and economically available via the Internet. GSW is an unprecedented collaboration of six leading earth science societies and one institute."
Be aware, though, that because this is a trial, you won't find the handy little red SFX links that will take you to the full text sources for other journals. To get those, go through the Library's webpage to GeoRef, where you will be properly authenticated.
