Museums around the world I think are very similar Brian, Museums don't always recruit from knowledge, they prefer a degree, about 9 years ago I seen a job advertised for the Liverpool museum, it was looking after their Maritime section and also in charge of Maintenance etc, I thought nothing to loose here and downloaded the application form, first question was what Degree I had and where from..... all in all I managed to fill a few box's in, name and address etc, the last one one was regarding the position, what or why would you be suitable for the position.......... I went to town on that one, strange I never heard anything back.
