It is difficult to keep track of the ‘open access’ discussion. An important source is the SPARC Open Access Newsletter, now edited by Peter Suber. The current issue contains an overview of 2003 developments.
What percentage of the journals or articles needed by the faculty at your university are unavailable except by interlibrary loan or private emails to lucky colleagues elsewhere? Let’s call this the “ullage” of the library, after the word for the empty space at the top of a wine bottle. The ullage of a library is the gap between what is directly available and what is needed.
Libraries are not ends in themselves, but serve the interests of the organizations of which they are a part. As university emphasis varies around research, education and career poles, we can expect to see libraries evolve to support those emphases more strongly.
