Currently, the Haskell language does not mention any libraries or facilities for using them. The standard prelude is meant to serve as a library but it lacks many important features. All Haskell implementations have begun to haphazardly include various libraries. However, these libraries have not yet been standardized across the different implementations and cannot always be used in a portable manner. We have produced a document which discusses some of the issues involved in designing a standard Haskell library and describes what we think the library should look like. We welcome any comments or suggestions teh Haskell community care to make. The document is available in postscript format by anonymous ftp: /pub/haskell/yale/libs.ps on haskell.cs.yale.edu and over the web: http://www.cs.yale.edu/HTML/YALE/CS/HyPlans/reid-alastair/libs/libs.html Alastair Reid and John Peterson Yale Haskell Project
