The purpose of these guidelines is to serve as a reference point for all players involved in the AEO-3 production process. The main aim is to ensure consistency in the quality of contributions to the report; avoid problems in the use of illustrations; and guide the editorial and review processes. The guidelines are relevant to all partners and stakeholders contributing to the AEO-3 reporting process. They should be used through all stages of the process: from data acquisition, drafting, writing editing, peer review through to design and printing of the finished product.
