I want the UMSF community to think about the concept of a Library
devoted to Space History. Perhaps, this is a function that is already
served by the Smithsonian Air and Space facility.
However, what concerns me is that there doen't seem to be one
main repository for all of the fascinating and significant data and
images and stories that I have seen displayed on the UMSF forum.
What does the community think about this concept? What can we
do to foster a library or an institute to serve as a entity devoted to
this subject that is dear to all of our hearts?

I think it's a great idea.
A few thoughts, though.
(1) I suspect you may mean "archive" rather than "library". Some libraries I know of have a habit of disposing of parts of their collections once said parts reach the end of their use-by dates, which in science can often be quite short. For example, I wonder how many of the various books on Mars published during the 1960s and 1970s you would still be able to find on library shelves?
(2) The Wayback Machine site (www.archive.org) is attempting a general archive of the WWW. Some of what they have to say
here is potentially relevant to what you seem to have in mind.
(3) What will the library/archive be trying to preserve? Books, disks, tapes etc on the subject-matter in question or the data contained in those books, disks, tapes, etc?
The two are not the same. For one thing anybody who can read can read a book, but given the passage of even a comparatively short period of time data in electronic formats may no longer be accessible, not merely because the media on which the data was written may have degraded but because the hardware to read that media may no longer be available (or at least in a functioning condition) to read it.
If the aim was to preserve the original materials then would require (in the case of the electronic ones) having the hardware to read those material available and still functioning. Not to mention periodic conservation measures to prevent the materials degrading.
On the other hand, preserving the data would require periodic migration of that data to newer and more up-to-date media. Plus you would need some kind of backup system to protect the data against catastrophic hardware failure.
Either way, both options are likely to be expensive and on-going exercises.
(4) What happens if such a library/archive acquires multiples copies of the same book, image, etc? Does it keep all of them or just one? Alternately, does it only keep selected ones? (Eg the best-preserved copy plus another less-well-preserved copy which was signed by the author.)
If the policy is to keep everything then eventually a large amount of shelf space and/or computing storage will be required.
Take the case of the Wayback Machine mentioned above, which takes the "preserve everything it can get its hands on" approach. Its
FAQ notes: "The Internet Archive Wayback Machine contains almost 2 petabytes of data and is currently growing at a rate of 20 terabytes per month. This eclipses the amount of text contained in the world's largest libraries, including the Library of Congress." (A petabyte is a million gigabytes.)
All that data is "stored on hundreds of slightly modified x86 servers".
A space history library/archive may not be quite that big, yet it has the potential to be very big, especially if the ambition is to preserve
both the data (eg images) & the media they came packaged in (eg books).
