That manuscript is a real historical treasure and I think it's great that it is made available for scholars worldwide this way.
It's really expensive, time consuming and sometimes even tiresome (and that means something coming from me) to have to drive or fly (or go by boat) long distances to get to historical sources or historic sites and spots. I can tell you, three of the most important spots for my main field of research are more than 3,000 miles away from where I live.
And then there are sometimes quarrels with the local authorities, may it only be a curator. Which permissions do I need? Can I see everything I need/want to see? May I touch or do I have to observe from a distance? May I take photographs or make copies? Will it cost me anything and how much? How much time can I spend?
This is such a relief for so many people working with these texts. Now at least the ones who don't need to see the medium first hand (for example to analyze the material) can work with much better conditions.
