Permit me to suggest once again that failure to resolve the functions of 
the archive (and of the archivist) can lead to a trap. More precisely, 
an archive is not a library - a library is not an archive. The obvious 
difference between them is accessibility; its corollary is reproducibility.

Imbibition prints and true Kodachrome slides are the most durable color 
photo schemes we know with Cibachrome a more practical compromise and 
color separation rather a different process. Cost and unavailability 
force compromises, but an archive should aim for preservation of the 
material it can obtain. That entails restricting access in numbers and 
in environment. In contrast, a library subject to similar constraints 
will choose one or more formats which provide most practical access; 
fidelity to the master is generally less important.

Even if both the library and the archive are to provide digital 
reproduction, their different objectives will dictate different 
solutions. Resolution, color fidelity, organization and other factors 
will lead to different solutions for different uses. A library's 
DVD-Video of Italian painting of the Renaissance might have a wide 
audience for a tour offering what amount to postcard-size images to fill 
a television screen. The counterpart in the archive might be a DVD-ROM 
with a fraction of the number of images each of which takes perhaps a 
hundred times the space and contains a color reference - at least a bar 

Of course, on this list we are aware of that distinction in audio. I 
trust that no one seriously suggests limiting an archive to 44/16 or 
trying to distribute 96/24 sound to the general public.
