Image Display: Image zooming

People have brought the problem up many times that it would be better if we could display images dynamically and be able to zoom in.

A quick and easy solution is Zoomify EZ (which is free) or other more expensive versions of Zoomify that have more features.

Zoomify will work with high resolution images relatively quickly. It works by saving the image in a mosaic of smaller images at different resolutions. It only deals with a few sections of the image at a time instead of dealing with the whole image, so there is very little lag. The speed is determined more by the computer and the internet connection than the size of the image itself.

With this software, the level of zoom is determined by the DPI of the image. It will allow someone to zoom in till the section they are viewing has reached the original DPI.
Since the free version of Zoomify uses flash, it also helps to prevent people from downloading the image. This can be a problem if your goal is to share the pictures. You will have to include a link to the original image to allow people to download it easily.

Zoomify can also work with Photoshop and there are many resources on-line discussing how:

Documentation and Good Management in Digital Libraries

This month is all about self-evaluations for me and my employees.  Because of this, I have been thinking about how a manager is supposed to show their work and their worth. The easy answer is to say that if the employees are doing well, then the supervisor is good. It could be that the employees are doing well despite a bad supervisor. An employee doing badly is also not a sign of a bad supervisor. So what tangible thing can I say makes me a good or bad supervisor? Throughout the year, I try to focus on the actions I take to make my employees' lives at work better. I try to give them direction, advice, and help make things easier. I also try to champion them. Things do not always work but I adjust. When I sit down to write my own evaluation, though, I end up writing about documentation. To me, that is a concrete indicator of a good supervisor. They care enough about the work, and their employees, to write things down and make a record. I want to challenge everyone to write

Bureau of Indian Affairs- Digital Collection

The Bureau of Indian Affairs is one of the oldest Bureaus in the United States.  It was established in 1824 by Secretary of War John C. Calhoun . While the history of the organization has been controversial, their records are open to the public.  This collection brings together letters distributed from the Bureau of Indian Affairs starting in 1832 and going on into 1966.

The Workload Iceberg for Digital Collections and Initiatives

In the last few weeks, I was asked to write a small paragraph explaining my area to others in the library.  I was happy to do this, as many people say they don’t know what my people do.  It’s sometimes hard to explain to others what we do without going into overtly technical topics and terms.  If we have done our job right, we’re practically invisible, which is the way it should be.  Anyway, writing the description made me realize why there is often a mis-match between what we do and what people think we do.  I’ll let you read the description yourself.  I’ve underlined the important bit. “Digital Resources is primarily an Open Access publisher.  We publish both born digital items (produced by students or faculty), and we scan to publish or republish old items. We curate digital collections through the whole digital life-cycle. Our work is a bit different from other departments because the more work we finish; the more work we create in having to maintain the collections. We’re no
