ACRL has made the entire College & Research Libraries archive freely available.
Here's an excerpt from the announcement:
"Digitizing the archives of the premier research journal for academic librarianship provides a tremendous new asset for our profession," said ACRL President Steven J. Bell of Temple University. "Creating and sharing this rich resource demonstrates ACRL's ongoing commitment to promote and deliver on the promise of open access. It is a treasure trove of content where the academic librarians of today and tomorrow will delve into our history, understand how we evolved and make new discoveries that could stimulate groundbreaking research and innovation of real benefit to academic librarianship."
C&RL archival contents from 1939 through 1996 were digitized through the generous volunteer efforts of the University of Illinois at Urbana-Champaign Library. The library's Digital Content Creation department performed scanning and metadata creation for the approximately 340 back file issues of the journal in 2011 and 2012. The digitized files were added to the journal's online presence with the financial assistance of the ACRL Friends Fund.
