I think we have had very interesting discussions based on our knowledge and experiences about how to manage the digital materials as librarians this week. Here are some of my thoughts.
I think if the community of a library is big, different formats of digital materials should be needed. Like the example of the Minnesota Historical Society Library that has been talked about by Brian in his post, Wisconsin Digital Collection has also provided different copies of every digital image. So images in smaller or bigger size is available to the users. When I made the tutorials for cataloging the digital images, I was asked to use some of them as examples and made them as clear as possible. Since they have four different sizes of each image, I will always use the largest one in the tutorial. Also, if the community contains different age groups, I think the size of the images and texts matters, too. So, maybe small libraries could preserve and provide one copy of the digital materials, then give the links of multiple choices in larger databases or organizations to the users. Thinking about DPLA, will that be a kind of service that it wants to provide in the future?
