[AV Media Matters] Preservation matters: CDs and cassettes

[rhaddad@cca.qc.ca]

Dear colleagues: I am new to the list and ask you to forgive me if I
mention
issues already addressed. I have 2 questions regarding best
preservation
practices:

1. the CCA Library sometimes acquires books and periodicals which have
a
CD-ROM inserted into a pocket at the end of the volume. For
preservation
reasons, we remove this and place it in a new plastic jewel box. With
separate labelling, shelving and retrieval, this becomes a fairly
labour-intensive procedure. Question: are we being too meticulous? What
are
the implications if we DON'T do this? (By the way, I have been
following
your discussion on labelling of CDs).

2. regarding proper storage of video and audio cassettes:  I find the
current literature contradictory and confusing. We leave video
cassettes in
their original cardboard protectors, encase the whole thing in an
acid-free
box, and shelve the cassettes upright on their long edge. Current
literature
tells us: a) paper and card boxes are susceptible to damage from insect
infestation; b) cassettes should be stored in acid-free boxes for
protection
from airborne dust & particles; c) cassettes should be shelved upright;
d)
they should be shelved horizontally. Question: any consensus on these
matters?

Those of you familiar with the Canadian Centre for Architecture know
that we
have excellent storage facilities for all materials, and two good
Conservation/Preservation departments (one for Library materials, one
for
works on paper). In the Library, we try to remain current regarding
preservation of magnetic and digital media.
