Astronomy & Astrophysics (A&A) is a monthly peer-reviewed scientific journal covering theoretical, observational, and instrumental astronomy and astrophysics. It is operated by an editorial team under the supervision of a board of directors representing 27 sponsoring countries plus a representative of the European Southern Observatory. The journal is published by EDP Sciences and the current editors-in-chief are Thierry Forveille and João Alves. Astronomy & Astrophysics was created as an answer to the publishing situation found in Europe in the 1960s. At that time, multiple journals were being published in several countries around the continent. These journals usually had a limited number of subscribers, and articles were written in languages other than English. They were less widely read than American and British journals and the research they reported had therefore less impact in the community. Starting in 1963, conversations between astronomers from European countries assessed the need for a common astronomical journal. On 8 April 1968, leading astronomers from Belgium, Denmark, France, Germany, the Netherlands, and Scandinavian countries met in Leiden University to prepare a possible merging of some of the principal existing journals. It was proposed that the new journal be called Astronomy and Astrophysics, A European Journal. The main policy-making body of the new journal was to be the "Board of Directors", consisting of senior astronomers or government representatives of the sponsoring countries. The board appoints the editors-in chief, who are responsible for the scientific contents of the journal. The European Southern Observatory was chosen as an additional body that acts on behalf of the board and handles the administrative, financial, and legal matters of the journal. A second meeting held in July 1968 in Brussels cemented the agreement discussed in Leiden. Each nation established an annual monetary contribution and appointed its delegates for the board of directors.
