Old Computer Books On Databases (Matlock DE4)

I'm offering many old computer books, covering a variety of subjects. These date from 1990s into early 2000s so, whilst they cover the basic technologies, they are not up to date with all the modern stuff. For example the book on CSS only covers v2.1.

With so many on offer, I've divided them into categories, though some may appear in more than one category.

I've indicated the year of issue and approx number of pages.

When replying please state which one(s) you would like. Collection from Matlock at a time to suit you.
