Erin, I think the answer to the accessibility question is increasingly NOT to try to make sure you have something for each identifiable segment of the population that may have different capabilities or limitations. Rather, it seems sounder to employ universal design in the creation of exhibits, using a variety of senses in each exhibit, thereby ensuring not only that a larger proportion of the total visitor population will be able to experience the exhibit in SOME way but also that a large percentage of the visitors will be able to experience it in SEVERAL ways. We've all heard and/or read the research results on how much of a message we retain if we only read it, versus reading and hearing it, etc. It just seems to make good sense that everybody will comprehend a topic better if they can receive it through more than just one sense. Of course, as one consultant put it, if they can't get into the museum from the parking lot, what you do inside doesn't make much difference! One reference that may be useful in this regard is Carol Hunter's recent "Everybody's Nature."
