- "Virtual Library"
- by (C) Billy Barron* <BILLY@vaxb.acs.unt.edu>
-
-
- A virtual library, in its simplest definition, is an electronic
- system that duplicates traditional library functions. If implemented
- correctly, however, a virtual library is much more functional,
- cheaper, and smaller than a normal library.
-
- What does this have to do with the Internet? Well, virtual library
- designers recognize that the Internet is an important part of the
- virtual library. The Internet will allow materials to be shared much
- more efficiently than InterLibrary Loan (ILL).
-
- Fully developed virtual library software is still several years away.
- The state of the art can be found in Gopher and the World Wide Web
- (WWW). Neither of these systems have addressed all of the library
- issues, but then again, they do not claim to. They are currently
- missing functionality to handle some of the more complex copyright
- issues, ILL, and a few other such things. However, these pieces of
- software are still very useful in the applications they are designed
- for, but should not be seen as a final solution for virtual library
- software in their current state.
-
- Several virtual library research prototypes are being developed. One
- of the more exciting ones is the NASA BOOKS project. BOOKS attempts
- to model a library. When you start it up, you see a reference desk, a
- catalog, and the book shelves among other items. It is my guess that
- a production version of the software will not be seen for 3 to 4
- years. It is being designed as a complete virtual library solution.
-
- For any of these virtual library systems to effectively work, it is
- critical that the current Internet resource discovery problems be
- solved. The IAFA (Internet Anonymous FTP Archives) Working Group
- proposal in front of the Internet Engineering Task Force (IETF) right
- now is a first step in solving the problem. Resource discovery is a
- hot area of research at the moment on the Internet so I expect we will
- see quite a bit of progress in this regard.
-
- Z39.50, the bibliographic control protocol, is a key technology that
- must be deployed before virtual libraries will be able to communicate
- with each other effectively. Several vendors are in the process of
- developing Z39.50 systems so we should see movement in this direction
- in the near future.
-
- Probably in the end, the difficult issues will be licensing and
- copyright, not technology. For any of this to work, it will require
- librarians and computer professionals to work together.
