            A note from the Publisher
          
        
        
          After thirty seven years BiTech
        
        
          Publishers Ltd. is closing down on
        
        
          December 31, 2019.  This  Decem-
        
        
          ber issue of Geotechnical News will
        
        
          be the last.  The Canadian Geotech-
        
        
          nical Society (CGS) will continue
        
        
          publishing a quarterly magazine
        
        
          working with Lisa Reny and her
        
        
          company
        
        
          
            Karma Link
          
        
        
          .
        
        
          In 1982 Geotechnical News started
        
        
          as a type written new sheet to pro-
        
        
          mote general information and activi-
        
        
          ties of the CGS.  It was separate
        
        
          from the technical content provided
        
        
          in the
        
        
          
            Canadian Geotechnical Jour-
          
        
        
          
            nal.
          
        
        
          The newsletter was converted
        
        
          to a glossy newsmagazine in 1983 at
        
        
          the Vancouver PanAm Conference
        
        
          and started to add technical articles
        
        
          on any topics related to geotechnical
        
        
          engineering.  Technical articles for
        
        
          Geotechnical News have not been
        
        
          peer reviewed.   The only require-
        
        
          ment has been that they were well
        
        
          written in French or English.
        
        
          In the years we have seen significant
        
        
          changes in the publishing industry.
        
        
          Desktop publishing has completely
        
        
          changed the production process of
        
        
          magazines and conference pro-
        
        
          ceedings are now almost entirely
        
        
          produced on USB sticks.
        
        
          We thank the advertisers for their
        
        
          continuous support and the editors
        
        
          who solicited the wide range of
        
        
          articles.
        
        
          It has been a very interesting and
        
        
          rewarding experience.  We are
        
        
          pleased we have been able to sup-
        
        
          port the ongoing success of the
        
        
          Canadian Geotechnical Society
