available online at the Internet Archive. You can browse the issues on the website, and even download individual issues. The collection also includes the Best Ofs and Dragon Annuals. Polyhedron, the magazine of the Role Playing Gamers Association, is also there in digital form. That's quite a trove!
Personally, I bought my last new issue of Dragon back in the '90s. Lackluster articles and a lame letters section with fanboy debates on casting for an imaginary Dragonlance movie led me to believe that the magazine had jumped the shark. Besides, I had been out of gaming for several years, and even though I would pick up the occasional find at a used bookstore, it would be years before I got into the OSR and back into gaming.
But I still look back fondly on those days of my youth, when seeing the issue in the magazine section at Waldenbooks at the local mall sent me thumbing through the pages and fumbling through my pockets for allowance money to buy the mag. Now I can relive that thrill of discovery of some new gaming goodness.
