I cannot find any markings or highlights in the text. The main text is in very good condition. BUT All of Pages 20 to 40 are missing. It looks like these fell out in the past. All the pages up to 48 can be pulled loose from the spine as a single pack of pages but can also be held in place by weight of other pages. The hard cover also has wear and a little damage.
BUT all the main text pages seem to be very good. There also seems to have been some liquid on some pages in past, particularly around the index pages.Book Overview
This book was released simultaneously with Release 2.0 of Mathematica and covers this very early release: Release 2.0. This edition maintains the format of the original book and is the single most important user guide and reference for Mathematica at its time of release back in 1991.
