Lecture Notes in Computer Science: Four volumes, hefty paperbacks--Price Reduced

Four volumes in a substantial and long-running series of books that are called \"Lecture Notes In Computer Science.\" They are all thick silver softcovers with red trim, red type and some white bands across the fronts. The earliest book is from 1990 -- #457 -- when the conference was in Zurich. Book 2 -- #970 -- is from September of 1995 in Prague. Book 3 -- #1123 -- is from Lyon, France, in August of 1996, and the fourth volume -- #1214 -- is from April of 1997 in Lille, France. Book #1123 is identified as \"Volume 1.\" All four volumes are published by Springer-Verlag, which has offices in Berlin, New York and other major cities. Although I have not scrutinized each page of the four books, it appears that these are unmarked, tightly bound, and without any names, notes, etc. All of the books are in English. Free shipping in the U.S. The information about the dimensions and weight are for one book, not all four. Price reduced by $10 on 10-31-25.
