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.
