Over-sized Items

     When the largest document a scanner can accommodate is
12.5 inches by 17.5 inches, there are bound to be documents that are too large
and must be scanned on other equipment. So far, there have been approximately 200
over-sized items in the All American Canal Project Histories Collection. This
means that for about every five items which fit in the Epson Expression 10000
XL scanner, about one of them will not fit. The photo below is an example of a
VERY over-sized item. Measuring approximately 6.5 feet wide, and 10.5 inches
tall, this map will need to be scanned on specialized equipment. As you can
see, by just taking a panoramic photograph of the map, the dimensions and details
are distorted and some of the information is lost. This is why these items are
set aside until they can be scanned on either a scanner with a larger scanning
surface, or a scanner which allows the feeding through of long documents. Scanning
of this map will likely be completed on an engineering scanner. Engineering
scanners essentially feed through a document while scanning it at the same
time. All oversized items in this collection are being noted so that way they
can be scanned together when all of the other smaller documents are finished
being scanned.
