The six issues of the Dragon Annual contained articles mostly geared towards the current edition of (Advanced) Dungeons & Dragons. Free with a subscription to Dragon magazine, the annuals were also sold separately.
One issue was published by TSR in 1996 and the remaining five were published by Wizards of the Coast/TSR in subsequent years.
The first four annuals were primarily for Advanced Dungeons & Dragons second edition while the last two were for Dungeons & Dragon third edition.
