Has this been covered before? I have added a lot to my collection of Radio Shack manuals
over the winter. It is now warm weather here on the east coast and that means lots of
humidity.
What are the reccomendations for humidity levels for long term storage of paper products.
I have the dehumidifiers running and have it down to about 45%, but they're struggling
to keep up. My basement is about 110 meters square and 2.2 meters high.
Thanks,
Kelly

It is the 100% humidity that will kill you. Unexpected basement flooding
is what you also need to worry about is a valid threat.

Just would like to add that a solution I've been thinking about is bag
sealing the things that may have to go in the basement. The bag itself
is 100% moisture proof and whatever small wear holes there are or
the tie around the bag opening would admit some air and therefore
humidity, but it would cut the air exposure rates down by a factor of
1000's to 1, I would think. May have to back it up with Dessicant in
the bag too. Uline.com, for one, can sell that in bulk for this purpose.
Seal the bag in the climate controlled area first and then put that in the
basement to start off well.

Since I'm a volunteer at the Computer History Museum, I thought this subject
would be best addressed by a professional archivist. I asked Allison Akbay
<akbay at computerhistory.org> for advice for vintage computer collectors in
storing documents. Here is her response:
------------------------------------------------------------------------------
The good news is the caring for books and other documents is something
that archivists, conservationists and Museum collection managers have
down pat as we have had hundreds of years experience at caring for these
types of things. Now caring for vintage computers is a whole new
field... ;-) [my smily face - Lyle]
There are some really wonderful references online, here are a few I
recommend:
American Institute for Conservation publishes brochures for the public
that are available online:
http://aic.stanford.edu/library/online/brochures/
Conservation online has a number of great resources run by a great
variety of Museums and archives:
http://palimpsest.stanford.edu/bytopic/genpub/
The National Parks publication Conserve O Gram is aimed at collections
in parks but is easily useable by the general public. All of the
Conserve O Grams are available online at:
http://www.cr.nps.gov/museum/publications/conserveogram/cons_toc.html
------------------------------------------------------------------------------
In addition, for those who live in, or are visiting the San Francisco Bay Area
in June, Allison is running a workshop on artifact and document care:
"June 21st at 2 pm I am teaching a artifact handling workshop at the
Museum which gives a basic introduction to document care" - Allison
