I looked at the archives The Rosetti Archive and The Ecclesiastical Proust Archive. When looking at these archives and various others I noticed some common features. Some are more focused on information that would be more useful to a user that is already familiar with a certain subject or discipline. It expects its’ user to already have the education that would most benefit their use of the archive. However if someone were using this same archive without the necessary background education they might not find the archive user friendly or even useful. On the other hand I also saw archives that focused on more of a broad user audience and not towards users of just one specific discipline. These archives were more user friendly, but when trying to find something specific the archive threw out an abundance of unnecessary information which its’ user would not find useful.
In conclusion I think archives can be very useful, you just have to find the one that works the best for you.
