We live in an age of blockbuster traveling exhibits which require substantial conservation work before, during, and after the exhibitions. There is no question that big exhibitions are necessary. To fight this would be unrealistic, and would not be in the interest of our educational work. If I wanted to be ironic I would say that fewer curators and more conservators might change the situation. But seriously, we need the opportunity of traveling exhibitions for research as well as for reaching the public.
Conservators can gain new knowledges and experiences.
The question is how can we reduce the burden. First, we can reduce the size of such exhibitions, limit the number of objects. This also has the advantage that one can display the objects more generously, so that ten people can stand in front of a painting. Second, museums must have more confidence in each other. If I trust an institution with a loan object then I fully trust it.
