We are finishing up a grant to digitize the historic maps at the North Carolina State Archives (government archives) and have been using a Graphtec CS600Pro, that we have been very satisfied with. The initial cost was $15,363 (bought with grant funds), but it is now 5 years old and is a true workhorse. See (http://www.graphtecamerica.com/). Our issue has been storage and getting IT support. Our original computer working with this scanner was terrific. However, each time ITS replaces it, it gives us computers that have insufficient processing power. We then have to complain over and over until they believe us and replace the computer again with a more powerful one. Even then, we often do not get the level of computing power that we really need to handle 1+gb files.
We have been storing our maps on DVDs, but now, at more than 800+ disks to keep up with, we are turning to SAN storage and dark archive storage. It has become a nightmare to keep up with what map is on what disk, especially once you have done the core collection and are now doing maps that are being accessioned today. It will take me some time to unload all the disks, especially since we have only around 10 maps per disk. We scanned at 600dpi, full color, for our master files. We present them as jpeg2000 images at http://www.lib.unc.edu/dc/ncmaps/ which is a site hosted by the University of North Carolina at Chapel Hill.
Once we have all our maps on the SAN and organized properly, we are going to send a copy to OCLC's dark archive for preservation storage. We want to get out of the business of replacing DVD's every 5 years (yes I know they say they are guaranteed for 100 years, but the archival industry recommends replacing the disk every 5 years, even with the "gold" media.

I would definitely look for a small grant to purchase your scanner. I don't think, for the amount you wish to scan, that an inexpensive one would be satisfactory. Also, once you have your project completed, you have invested in a piece of equipment that will last for a nice while. You will also probably get better support from a good vendor or manufacturer, this way.
I am about to wander into an area that I rely on colleagues to guide me. But you may be talking about two types of software, one for digitization of your images, and another for archiving, and retrieving the digitized images. There are open access shareware viewers available, or the provider of the equipment can provide guidance on purchased software.
The digitization software can allow the creation of metadata to identify the images. Others on this list can give more detailed information about some of this, but I would recommend as high-quality of a scanner as you can afford. This will probably represent the single largest cost. The electronics and optics along with the mechanical operation keep the cost of this equipment high. And as one of my colleagues who knows this stuff reminds me, the server space to store files is cheap. I will forward your message to him because he can give more specific guidance than I can do.

Hello all,
Our library has about 5,000 historic map images available online but we
have over 35,000 more maps that we want to make available online so I'm
reaching out to fellow map librarians for ideas on how to achieve our
goal in a cost effective manner. With that in mind, I have two main
questions:
1. Are there any economical wide format scanners out there? From what
I've seen, a scanner is going to cost several thousand dollars that we
don't have so I thought I would see if there are some other solutions
out there. I can have some maps scanned at nearby in institutions, but
I don't want to overwhelm them. It appears that a grant hunter is in my
future!
2. What is available for an open source CMS application to act as a
map/image server? We currently use a makeshift photo gallery software
that allows for using bandwidth saving tools such as Zoomify and batch
uploading. We'd love to add links for users to download full images,
but can't offer that with all maps due to copyright issues. I'd love to
find a CMS that would allow us to batch upload images into categories,
add the geodata and select which ones could be fully downloaded as well
as using some kind of bandwidth saving measures. Any thoughts on this?
I appreciate any input that you can offer and I thank everyone for there
generous input in the past.
