Thank you, Bob, for bringing this topic to our attention.
Haviva, John, Doug and Linda have added important aspects to the discussion. Many institutions do not have the resources to generate a comprehensive collection of virtual images and sharing is a great idea. However, as all of you already pointed out, there are a few issues and problems that need to be solved.
First, creating a national or even better international database needs a financial and technical framework that is probably beyond a single institution. It would make sense to get AAA, NIH or NSF support for this.
The other problem raised by Linda and others is the copyright issue. One possible solution would be to publish the various virtual slide collections under a Creative Commons License (http://creativecommons.org). That means the copyright stays with the original creator of the resource, but users are allowed to use the collection with specific limitations (At U of Michigan we are using non-commercial, attribution and share alike; http://creativecommons.org/licenses/by-nc-sa/3.0/). There are several different Creative Commons Licenses and that may complicate the issue.
There is a worldwide interest in switching to virtual microscopy for histology, embryology and pathology instruction. Many of the requests I am getting for sharing our virtual slide collection are from universities all over the world. Especially new medical and dental programs are interested to instruct their students using virtual microscopy and not to acquire expensive microscope and slide sets. Any solution should therfore include "customers" from non-US countries, specifically third world countries.
As temporary solutions, besides our open website (http://histology.med.umich.edu/schedule/medical), our virtual slides are accessible (but not downloadable) from the image database of the American Society for Cell Biology (called The Cell, an image library: http://www.cellimagelibrary.org) and I also have created a local, password-protected server here at the University of Michigan from which colleagues, who contact me to request access, can download our collection (about 200 GB). The second solution has worked for colleagues in the US and Europe, but may not be feasible for locations with a slow Internet speed. I have used mailing of a small portable hard drive for countries with slow or unstable Internet connections. However, after my hard drive spent several months in Brazilian customs, I am trying to avoid this option. Therefore, delivery of large datasets is another, more technical concern.
I'd be happy to join the effort of a national/international virtual slide database and like to offer our/my experience in sharing virtual slide collections.
All the best
Michael

This sounds like a great idea, but are the materials copyright protected. Would we be able to create a database from it?
If so, then would AAA be responsible for "management" of the images?
Just wondering how to move forward.

I just wanted to chime in that we would also be interested in the availability of such a resource and have virtual slides we'd be willing to contribute. Ours were scanned by Aperio some years ago. I'm not an expert at other formats for such slides and wonder if slides would have to be catalogued by format for ready access and whether format conversion is either necessary or desirable.

The idea of sharing virtual microscopy resources has been brought up from time to time in published articles and informal discussions among histologists. Is a national repository of virtual slides where any course or program director could obtain slides a good idea? What would be the best way to create such a resource? What are the impediments to creating such a resource?
