Only the new publications are mentioned. The proceedings of the ALADIN workshops and the joint ALADIN & ALATNET Newsletters are not considered here, nor are the extended abstracts involving only one centre and no young researcher, to avoid a too long list.

The five research centres, or ALATNET partners, are numbered as : 1. Toulouse (Fr), 2. Bruxelles (Be), 3. Prague (Cz), 4. Budapest (Hu), 5. Ljubljana (Si).

The acknowledgement notice does not appear in extended abstracts, as for other grants, nor in publications involving only one ALATNET centre, for directives were not at all clear on this point.
