Evidence
Some great information there.
To make the project worthwhile, I think that all the evidence has to made available, including the documents (eg, maps, memos, photos). Otherwise, all we have are the extracts from the evidence that Macfarlane chose to put in his book and the copies of documents that MacFarlane chose to put in his book.
One thing ALPA obviously cannot do is attempt to include every book/article/opinion that has been written about this accident. This would make the task a never-ending one. So the best approach might be to leave all that out, and concentrate on the primary material. As I understand things, it's held by Archives NZ at Wellington, and they might be prepared to assist. (I'm sure that there would be many librarians around NZ who would be very pleased, as it would save them dragging a supermarket-trolley's worth of big volumes up from the basement everytime someone gets interested in Erebus.)
