If you're interested in knowing the impact of technology on cataloging, there's good news and bad news regardless of how you look at things. If technology intimidates you, the good news is that the essence of cataloging is not going to change in the foreseeable future. The bottom line is that technology is changing the resources people need access to as well as the tools and procedures used by catalogers. However, the conceptual process of cataloging will remain much as it has been for a long time. The reason has a lot to do with how people like to interact with information resources.
People like to be able to ask for resources by name - in other words, a title.
People also associate individuals or groups of individuals with information resources - in other words, authors. People want to be able to find information resources that are about the same thing - that is to say they need to be able to find things written on the same subject. My point is that the basics of providing access to information resources won't change anytime soon. Technology has made life easier even for people who don't particularly like computers. It is no longer necessary to spend countless hours filing cards and typing labels.
