Although the principal manner in which UNIDROIT accomplishes its statutory goal of unifying and harmonising the law consists in legislative drafting, a number of the Institute's other activities, for a long time considered “ancillary” to the unification of law, are increasingly seen as an indispensable complement to the preparation of international instruments. At a very early stage, at a time when information technology as we know it today would have been regarded as belonging to the realm of science fiction, the Institute embarked on a policy designed to disseminate information on the unification process through an editorial venture which has gained in importance over time. I shall here focus on one such “ancillary” activity, relating to UNIDROIT publications.
