Cover Notes: There is some light and very minimal wear at the edges and corners (which is completely normal for old books due to storage). The cover is intact, has not suffered major tears or obvious misuse, and the colors are still bright and retain their gloss. 3. Is the Book Rare? The answer depends on the "type" of rarity: Materially/Commercially: The book is not rare with astronomical prices or of exorbitant financial value in the precious collectibles market; hundreds of thousands of copies were printed in the nineties as part of Borland's famous software packages. Historically and Technically: This book is currently considered a "Retro/Vintage Tech" piece. Due to the passage of decades and most people discarding old software manuals, finding a physical copy in clean condition like this is rare and difficult today. 💡 Summary: The book holds significant sentimental and historical value for fans of programming history, vintage computing, and archiving classics, but it is not rare in terms of high financial value.
