This first issue of volume 23 presents three papers from rather different domains of academic librarianship.

Whilst we may all be rather confident about the advantages of Open Access solutions for scholarly communication, this concept has from the beginning been received with mixed feelings by the developing world. On the one hand their financial means are even more limited than those of the developed world, so the benefits of Open Access should be highly welcome. For their own publications, on the other hand, we often witness some resistance due to the suspicion that these new publication channels could have a discriminatory effect on their research in comparison with that of Western research groups that can afford to publish in the commercial journals. The first paper of this issue studies the situation of Open Access in the developing world, from the point of view of Bangladesh.

The second paper presents an analysis of the problems encountered by cataloguers of cartographic material when describing the various intellectual responsibilities of the people who have collaborated in the realization of the maps. In many cases it is not straightforward to determine who is the principal author, and what are the precise contributions of the secondary authors. This problem arises in old maps as well as in modern digitally produced ones. The paper offers a detailed discussion of the corresponding relator codes in the UNIMARC manuals.

The third paper touches on the important problem of linking scientific papers with the full set of research data on which they are based. Research ethics increasingly requires accessibility to these data in order to ascertain the ver­acity and replicability of the conclusions of the claims made in the papers. The German EDaWaX project launched an investigation of the data availability policies of a set of journals in economics, and our paper presents the highlights of their analysis. Attention is given not only to the theoretical formulation of those policies, but also to the (sometimes disappointing) realization of them in practice.
