It would certainly be nice if they were available online buckhyne but that would be an absolutely mammoth task. The crew agreements are each a sizeable bundle of of documents, although the TNA holding is only a small proportion it constitutes a massive amount of paper.
As far as 'should be online' is concerned, I'm sure we all feel like that about the documents we're particularly interested in but in reality, priority must be given to those that provide information about the greatest number of people to the greatest number of interested parties. TNA holds literally millions of documents, it would be an impossible task to digitise everything.
