vendor to preserve audio tapes

["Jo Anne Martinez " <carino@xxxxxxxxxxx>]

I am working with a small manuscripts collection in Flagstaff, Arizona.  
They hold about 60 to 70 open reel tapes and about double that number of 
cassette tapes ranging in age from about 5 years old to more than 20 
years old.  For the most part these are field tapes made by two or three 
anthopologists of oral history and/or music of Asian, Hawaiian and 
Native American dance.  As part of a small grant we have some money to 
preserve these tapes.  I know that the standard is to produce an analog 
master on a 10" open reel.  Are most companies now advising that there 
be a digital (CD-R) use copy?  What are the charges for such copying?  I 
am not on the list so please reply to me directly at carino@xxxxxxxxxxx

Thank you.
