This paper investigates the similarities and differences between two important ideas in information processing and knowledge utilisation. Those ideas are [critical thinking] and [information literacy]. This suggests that [information literacy] and its associated procedures could significantly augment current instruction in [critical thinking] and indeed, the possibility has been explored by some authors in the current literature. A merging of the two ideas would involve [information literacy] providing tools and techniques in the processing and utilisation of knowledge and [critical thinking] supplying the particulars and interpretations associated with a specific discipline. This type of integration could lead to instructional programs similar in concept and application to those in research methodology where methods from statistics are integrated with the techniques and skills associated with a specific discipline. The development of a curriculum of this type would change functions and perceptions from private, individualised mentation, now associated with [critical thinking], to a more easily learned and practiced process suitable across the breadth of disciplines.

  "Old models of library operation may disappear, but that does not mean they can't be replaced.  Academic libraries' central book model is temporarily insulated by high prices, but change will come just the same.  The time provided by this insulation should be used to explore sources of content like local special collections with clear ownership and distribution rights.  Without restrictions like those imposed by many third party vendors, special collections can provide a proving ground for next generation interfaces and services. This home-grown expertise within libraries can then be applied on a wider basis in the future.                 The examples and efforts discussed in this column share one thing at their core, and that is that they are services made by libraries, for libraries.  As a collective institution, libraries have great expertise in building sustainable preservation systems capable of lasting many years.  Third party vendors do not have a proven track record on building long term preservation systems for electronic resources at this point in time.  By placing our trust, funds, and collections in the hands of those third parties we turn libraries into middlemen.  For the short term gain of providing easy access to next generation library services, we risk disintermediation by those vendors and removal from the service equation entirely.  Libraries of all types and sizes can look inward and grow from our strengths.  Major publishers and content providers aren't likely to allow new services with the same scope libraries enjoyed in the past.  Fortunately, special collections and collaborative efforts are accessible to even the smallest library as perfect opportunities for gaining relevant experience and expertise.  By basing that experience and expertise on homegrown services built by and for libraries, they can ensure a sustainable future of next generation services."

In keeping with that spirit, The U.S. Geological Survey (USGS) has publicly released more than 161,000 digitally scanned historical maps spanning in excess of 130 years and covering the conterminous lower 48 states. This Historical Topographic Map Collection provides a comprehensive repository of the landscape of our Nation and tracks changes through time, providing essential clues critical in the understanding of our Nation's topography, geography and development.
