DL week 1 required reading notes

Leonardo Candela et. al. (2007) Setting the Foundations of Digital Libraries. D-Lib Magazine 13(3-4), March/April 2007. http://www.dlib.org/dlib/march07/castelli/03castelli.html

I feel that this is a introductory essay of digital libraries. Firstly, the author talks about the evolutionary definitions of Digital Libraries. Then, he differentiate system notions, that is digital library, digital library system and digital library management system. This is part is helpful for me, because I used to think they indicate the same meanings. Thirdly, six main concepts and four main roles of actors are mentioned in digital libraries universe. It took me some time to understand the four different roles in DL. I am a little surprised that librarians are DL end-users, I thought they were designers before. so What we do is DL is just to use it ? This is disappointing.

well, this essay mainly talks about Digital Libraries Initiative launched by National Science Foundation. After reading it, I feel that the author speaks about DL from the perspective of computer scientists. In the essay, most of the content mentions how good the computer scientists are, how computer scientists help librarians out of predicament. Computer scientists has done most of DL work, while the only thing that librarians do is to "make them choose content descriptions from a controlled vocabulary of terms". This is my emotional feelings after read it, maybe the author treated both careers fairly. I feel very sad, since I thought librarians are the main power in the construction of DL. However, from the words of the author, he consider librarians just help computer scientists built DL. Besides, in the last graph, he said,"as models for new libraries, like the ACM Digital Library for computer science emerge.....", Do Library Science Education have to emerge with computer science? These are my own feelings, perhaps I do not totally understand the essay, maybe I am extremely sensitive.

Christian Lupovici. (2008) The growth of the role of librarians and information officers in digital libraries. Digital Libraries, Fabrice Papy (eds). ISTE and John Wiley & Sons, Inc.
Questions: What is the different responsibility between librarians and information officer? Can librarian be called "Information Officer"?
It is a good point to mention that librarians should preserve digital documents in the long-term. Digital preservation is an important topic in Digital Libraries, since lot of unforeseen incidents may happen in the future. How to preserve? Use what devices? How to deal with accidents? I do not know current digital preservation, I thought digital information is preserved on hard disks. But the expectancy of hard disks are short , only about three years.

BORGMAN, chapter 2. IsItDigitalorIsitaLibrary.pdf
Borgman puts close examination on the term" Digital Library". She analyzes the definition from the perspective of research and a library-practice. The explanations solve my suspicions that why we talks much about DL technology. Currently, computer power set the foundation of the development of digital libraries. We need technology to realize information services in digital form through Internet. However, I am a little worried that more and more digital libraries are build up now, dose that mean the society need less librarians? What dose the library look like in the future? A library without librarians? Since the number of old readers are decreasing and the number of internet-readers are dramatically increasing, less users will visit physical libraries. I am worried about the future of this career.
