How do you get Dungeons and Dragons first edition?

Answer 1

The most likely places to find copies are eBay and used book stores. A few game stores, including some online retailers like Noble Knight Games, also sell out-of-print role-playing games.

A lot of out-of-print D&D products were available for purchase in PDF form online until Wizards of the Coast decided to abruptly pull all PDF sales after catching a group of pirates distributing a newly-released Dungeons & Dragons 4th edition book. It is no longer possible to legally give the copyright holders any money for old D&D products.

It's important to know what you want. There are three different games that could arguably be called "Dungeons and Dragons 1st edition": Advanced Dungeons & Dragons (AD&D) 1st edition (consisting of a large number of books and boxed sets published between 1977 and 1989), the original Dungeons & Dragons Basic Rules (a rule book and a boxed set including the rule book, both published in 1977) and the original Dungeons & Dragons game (a box with three rulebooks published in 1974), sometimes called the "Dungeons & Dragons Collectors Edition." AD&D material is widely available. The original Basic Rules are harder to come by. Original D&D rules sets are easy to find on eBay but usually go for somewhere over $500.
