Front cover of ACMLA #Bulletin No. 19 Sept. 1975. The present cover illustration was traced from a computer-produced map. The initial computer map was produced in a two stage process which consisted of digitizing a map of Canada and running the data with a fortran programme to produce the map. The programme initially calculated the distance between each digitized point and Vancouver. The square root of the distances was taken and a new map was constructed on the Cal comp plotter using the square root products as distances. As a re-sult, the map illustrates Vancouver's view of Canada. Note: In 1975 the name of ACMLA was “The Association of Canadian Map Libraries” (A.C.M.L.)

COVER CHANGES
Cover changes have been few and far between in the Bulletin.
This issue begins what is hoped to be a focus of interest. textual part of the cover will not be changed unless someone wants something different. The graphic in the box will change! In every issue, there will be a new map, picture or other graphic
--- no cartoons! The graphic will be of broad interest where possible and be complemented by a brief discussion in the editorial comments. If you have any graphics that you think would be suitable, please send them in with a brief description.
