During the recent years the number of international contests in astronomy for secondary school pupils (usually known as Olympiads) has had an increasing tendency. More precisely, at present there exist three Olympiads which are planetary oriented. Bearing in mind the efforts done by the present authors to prepare collections of these international problems for the pupils from Serbia it is easy to understand the quantity of work which is necessary for collecting as many problems as possible. In addition, providing new telescopes implies preparing manuals for their use. In order to have an accessibility of all that material digitisation appears as something indispensable.
