Algol W was designed as a successor to Algol 60, closely based on A Contribution to the Development of ALGOL by Niklaus Wirth and C. A. R. Hoare. It includes dynamically allocated records, string handling, complex numbers and a standard I/O system. A description of the Algol W Language as at 1972 can be found at Algol W Reference Manual 1972 on bitsavers.org page. Dabcanboulet's Algol W @ Everything2 page contains an excellent history and tutorial.
