International Astronomical Union - National Members
There is great difficulty giving a list of National Members of the International Astronomical Society with their dates of joining as we shall now explain. The first problem is that countries are not fixed over the period during which the International Astronomical Society has existed, for example Yugoslavia joined in 1935 but after the country split into several different countries, Croatia joined in 1994, Macedonia joined in 1998, Serbia joined in 2003 while Slovenia and Bosnia Herzegovina do not appear to have joined. We therefore list countries such as Serbia as joining first in 1935 and again in 2003. There is, however, another problem is giving the list below, namely that the International Astronomical Union is not always consistent in the dates it gives at different times. For example some lists give 1948 for the date when India joined, other lists give 1964.
