     We have found that after several years, the glue in double sided tape
     begins to deteriorate and expand beyond the bounds of the tape, and
     find it unwise to use double sided tape anywhere near the vicinity of
     maps. Perhaps new technology has improved such "archival" tapes, but
     as a practice, we do not use it. Perhaps for temporary displays, but
     not for long term "preservation." We are now correcting what was
     preserved years ago... Alice Hudson <a href="/scripts/wa-UGA.exe?LOGON=A3%3D9806%26L%3DMAPS-L%26E%3D7bit7BIT%26P%3D62319%26B%3D--%26T%3Dtext%252FplainTEXT%252FPLAIN%3B%2520charset%3DUS-ASCII%26pending%3D" target="_parent" >[log in to unmask]</a>

For archival double-sided tape, we have used
        Hollinger Corporation
        P.O. Box 8360
        Fredericksburg  VA  22404-8360
        PHONE 1-800-634-0491
        FAX 1-800-947-8814
 
We have purchased the rolls of tape in as small of quantities as 1-2 rolls
at a time, since we don't use them much either.
