This introduction provides an overview of the discourse on alternative agrifood movements (AAMs) to (1) ascertain the degree of convergence and divergence around a common ethos of alterity and (2) context the chapters of the book. AAMs have increased in recent years in response to the growing legitimation crisis of the conventional agrifood system. Some agrifood researchers argue that AAMs represent the vanguard movement of our time, a formidable counter movement to global capitalism. Other authors note a pattern of blunting of the transformative qualities of AAMs due to conventionalization and mainstreaming in the market. The literature on AAMs is organized following a Four Questions in Agrifood Studies (Constance, 2008) framework. The section for each Question ends with a case study to better illustrate the historical dynamics of an AAM. The literature review ends with a summary of the discourse applied to the research question of the book: Are AAMs the vanguard social movement of our time? The last section of this introduction provides a short description of each contributing chapter of the book, which is divided into five sections: Introduction; Theoretical and Conceptual Framings; Food Sovereignty Movements; Alternative Movements in the Global North; and Conclusions.

Alvin Hansen and John Williams’ Fiscal Policy Seminar at Harvard University is widely regarded as a key mechanism for the spread of Keynesianism in the United States. An original and regular participant, Richard A. Musgrave was invited to prepare remarks for the fiftieth anniversary of the seminar in 1988. These were never published, though a copy was filed with Musgrave’s papers at Princeton University. Their reproduction here is important for several reasons. First, it is one of the last reminiscences of the original participants. Second, the remarks make an important contribution to our understanding of the Harvard School of macro-fiscal policy. Third, the remarks provide interesting insights into Musgrave’s views on national economic policymaking as well as the intersection between theory and practice. The reminiscence demonstrates the importance of the seminar in shifting Musgrave’s research focus and moving him to a more pragmatic approach to public finance.

CD‐ROM technology, introduced to librarians in the US four years ago, has taken hold as a support tool for technical processing and public services activities. In the interim, librarians and vendors have worked together to improve services and systems and develop new products in response to user needs. Further developments will depend upon librarian initiatives, vendor efforts to exploit other types of optical technologies to full advantage, and the development of standards that will assure uniform quality and acceptance.

As CD‐ROM becomes more and more a standard reference and technical support tool in all types of libraries, the annual review of this technology published in Computers in Libraries magazine increases in size and scope. This year, author Susan L. Adkins has prepared this exceptionally useful bibliography which she has cross‐referenced with a subject index.

Security is becoming an increasingly more important concern both at the desktop level and at the network level. This article discusses several approaches to authenticating individuals through the use of biometric devices. While libraries might not implement such devices, they may appear in the near future of desktop computing, particularly for access to institutional computers or for access to sensitive information. Other approaches to computer security focus on protecting the contents of electronic transmissions and verification of individual users. After a brief overview of encryption technologies, the article examines public‐key cryptography which is getting a lot of attention in the business world in what is called public key infrastructure. It also examines other efforts, such as IBM’s Cryptolope, the Secure Sockets Layer of Web browsers, and Digital Certificates and Signatures. Secure electronic transmissions are an important condition for conducting business on the Net. These business transactions are not limited to purchase orders, invoices, and contracts. This could become an important tool for information vendors and publishers to control access to the electronic resources they license. As license negotiators and contract administrators, librarians need to be aware of what is happening in these new technologies and the impact that will have on their operations.
