Since 1997,all book proposals have been refereed byspecialist reviewers as well as by the Society’s Books Editorial Committee. If the referees identify weaknesses in the proposal, these mustbeaddressedbeforetheproposalisaccepted. Once the book is accepted, the Society Book Editors ensure that the volume editors follow strict guidelines on refereeing and quality control. We insist that individual papers can only be accepted after satisfactory review by two independent referees. The questions on the review forms are similar to those for Journal of the Geological Society. The referees’ forms and comments must be available to the Society’sBookEditorsonrequest. Althoughmanyofthebooksresultfrommeetings,theeditorsareexpectedtocommissionpapersthat were not presented at the meeting to ensure that the book provides a balanced coverage of the subject.

It is the oldest national geological society in the world andthelargestinEurope.ItwasincorporatedunderRoyalCharterin1825andisRegisteredCharity210161. The Society is the UK national learned and professional society for geology with a worldwide Fellowship (FGS) of over 9000. The Society has the power to confer Chartered status on suitably qualified Fellows, and about 2000 of the Fellowshipcarrythetitle(CGeol).CharteredGeologistsmayalsoobtaintheequivalentEuropeantitle,EuropeanGeologist (EurGeol). One fifth of the Society’s fellowship resides outside the UK. To find out more about the Society, log on to www.geolsoc.org.uk.
