Institutes, both in the Netherlands and abroad, like for instance cartographic firms,
requesting information on the Rotterdam port, and last but not least pupils of
primary and secondary schools. It is notably to this last category that in the past
leftovers of former editions of the map were distributed.
About 5 per/cent of the map was sent to schools in 1971. The number of requests
was so considerable, and answering them so laborious, that in 1972 the Port Manage
ment will participate, together with some öther big transport companies in the Nether
lands, like the KLM/Royal Dutch Airlines, and the Netherlands Railways, in a founda-
tion that will centrally deal with all the requests for information from Dutch schools.
This foundation will also have as one of its tasks multiplication of the Rotterdam/Euro-
poort map adapted for education purposes. In 1971 the requests from schools outside
the Netherlands came mainly from Belgium, the United Kingdom, the Federal
Republic of Germany and Denmark.
In 1971 about 2000 copies of the map were sent to the town hall just as to the Port
Promotion Foundation. The latter distributes the map when its own resources of map
material are temporarily exhausted or as supplementary information. Attendance at
congresses in Rotterdam strongly fluctuates - it is estimated however, that about one per
cent of the maps goes to congressists. The Rotterdam Tourist Information Office is but a
small customer - it buys only some hundreds of copies a year. Harbour-cruise
companies and other private transport companies which organize tours of the harbours
by coach take about 10 percent of the total amount. The greater part of the maps is
bought in quantities ranging from ten to several thousands by companies in the harbour
areas: in 1971 about 40 percent. The rest, about 33 percent, is divided among visitors of
the port (through the Port Management) and institutes from the Netherlands and abroad
asking for information. The number of requests from the Netherlands dominates here.
The ANWB tourist route map is printed separately; its printing, amounting to 22 000
copies, is not included in the stated 100 000 copies of 1971
Rotterdam is a world port and as such its shipping-lines and business relations
extend all over the world. Its visiting card, in the shape of this map, has the world for a
distribution-area. The map is, thus executed, a magnificent introduction, not only for
the Rotterdam port, but also for its cartographic skill.
