Bibliography

This bibliography is the product of numerous sources, searches and cross-references by Peter Asaro in 1999. It corrects several omissions and errors in the bibliography of W. Ross Ashby that was published in The Cybernetics of Cybernetics (1972, p. 24). According to Peter, it still lacks several book reviews and possibly yet undiscovered works.
