Whatever their specialisation, research scholars and political science teachers are confronted on a daily basis with the need for information on means of locating texts or sophisticated bibliographical notes, research procedures in statistics, electoral results and various other data on current affairs. To meet this need, they avail of libraries, government agencies, private institutions and statistical data collections of great diversity, as well as numerous compilations of bibliographical references, abstracts of published articles and specialised indexes. Fortunately enough, they may also avail of the informal assistance of well-informed persons who allow them to save time while engaged in amiable conversation.
