verisimilitude has a brief review here: http://verisimilitudes.net/2019-06-15 The homepage of a project to retypeset it (much like existed with SICP) has some advertizing print on it: https://web.archive.org/web/20051216163615/http://thinking-forth.sourceforge.net/ I don’t believe there is sufficient difference between Forth 83 and ANSI Forth so as to make it obsolete, and you likely wouldn’t be reading it to learn Forth anyway. Then again I have not read this book and do not know Forth.
