R. Strijbos, head of the computer section of Mathematics, hopes and expects that the remaining, unchecked, tapes are also undamaged. 'However it is a time-consuming job to look at all back-ups. Each tape takes approximately four to six hours. That will keep us occupied for a while yet.'
To the great relief of the Mathematics department the safe was taken from the blackened part of the TW/RC-building two weeks ago. The safe turned out to have withstood the fire well.
