Product History

The Dungeons & Dragons Rules Cyclopedia (1991), compiled and developed by Aaron Allston was the triumphant finale to the BECMI edition of D&D (1983-85). It was published in November 1991.

The End of Basic D&D. By 1991, Basic D&D was TSR's longest running roleplaying line. TSR traced the history of the game back to the release of the original D&D (1974). Even if you don't count that, the first game labeled as Basic D&D - the J. Eric Holmes Basic Set (July 1977) - appeared five months prior to the release of AD&D's Monster Manual (December 1977). It had since undergone two major revisions: the Tom Moldvay D&D Basic Set (1981), which was part of the B/X release, and which kicked off Basic D&D in its modern form; and the the Frank Mentzer D&D Basic Rules Set (1983), which was the first book in the BECMI revision. 

Basic D&D had sold incredibly well at first, back in the late 70s and early 80s. Thanks in large part to the extensive publicity that D&D received from the James Egbert affair, new players were flocking to try out the game, and most of them went to TSR's introductory game - Basic D&D. That interest was in large part what led to the creation of the B/X and BECMI editions of the game, each of which expanded Basic D&D to allow for even more long-term play.

Unfortunately for Basic D&D, the pendulum began to swing toward AD&D as time went on. By the mid-80s, when popular books like Unearthed Arcana (1985) and Oriental Adventures (1985) were released, AD&D was clearly in ascendency, and Basic D&D was increasingly becoming the unwelcome relative who'd overstayed its welcome. The B-series ("Basic") adventures largely ended in 1985. The rest of the BECMI coded adventures finished up in 1987; other than the production of two final introductory adventures, B11: "King's Festival" (1989) and B12: "Queen's Harvest" (1989) a few years later. The "GAZ" line of Known World setting books then stumbled to a halt in 1991, with just one book published in each of the last years.

Although there were some new efforts like the "DDA" adventures (1990-91) and the Hollow World Setting (1990-92), it was clear that Basic D&D's flame was quickly fading.

A Black Box and a Hardcover Book. TSR tried to revive Basic D&D one last time in 1991 with a pair of new rules releases. The first was The New Easy to Master Dungeons & Dragons Game (1991), called alternatively the "Black Box edition," the "fifth edition," and "ten-seventy" (its product code, 1070) internally at TSR. It was a boxed D&D set that TSR described as "the first truly introductory version" of the game (as they had with every other "Basic" version of the game). The Black Box used cards to teach the game, something that had been advocated by Lorraine Williams based on the SRA reading programs (1957).

The Black Box is reported to have sold quickly and well. Approximately a half-million copies were purchased worldwide. It was also supplemented by a set of adventures that were almost boardgame-like with their colorful dungeon maps and figures. Unfortunately, the Black Box had one problem, the same problem that D&D "Basic" sets always had: it was limited in level, though it actually went up to 5th level, a bit higher than Basic's 3rd-level standard.

This limitation dovetailed nicely into TSR's other major plan for Basic D&D in 1991. Though the BECMI set of Basic D&D rules had always been well received, everyone thought it was quite troublesome to go through seven booklets totaling 368 pages when trying to track down a specific spell or magic item. Thus TSR decided to compile all of the rules into one hardcover book. The Rules Cyclopedia was the result - and it also offered somewhere for the Black Box players to go when they finished with fifth level.

Ironically, this was reportedly the exact same setup that Gygax had planned for the J. Eric Holmes Basic Set and also for AD&D, way back in 1977.

The Compilation. The Rules Cyclopedia is a compilation of the D&D Basic Rules Set (1983), the D&D Expert Rules Set (1983), the D&D Companion Rules (1984), and the D&D Master Rules (1985). It contains not only the rules from those boxed sets, but also the monsters, making the Cyclopedia one of two great sources for Basic D&D monsters, the other being the Creature Catalog (1986, 1993). Rules for skills and magic item creation from the "GAZ" Gazetteers (1987-91) are also included, making the Cyclopedia a truly massive compilation of about a decade's worth of Basic D&D rules.

The Immortals Rules (1986) are notably not included in the Cyclopedia, although it does contain seven pages from the Master Rules that include basic information for immortals, including rules on PCs ascending to those lofty ranks.

Rules on jousting in tournaments and on artifacts were also left out of the Cyclopedia.

Not an Introductory Book! Unlike every other iteration of Basic D&D, this one was not intended to be an introductory roleplaying book. It was instead a reference for Basic D&D play, which matched TSR's thinking about the AD&D 2e rules.

Expanding the Known World. The Cyclopedia doesn't expand the Known World in any notable way, but it does include a rather impressive atlas, featuring 16 full color maps, including the maps from the Gazetteers and the world maps from the Master Rules and the Hollow World Campaign Set (1990).

Future History. The Black Box rules and the Rules Cyclopedia got some joint support in the form of the "Thunder Rift" series of low-level adventures (1992-93). The Rules Cyclopedia also was supplemented with a few boxed releases, the most notable of which was Wrath of the Immortals (1992), a new set of immortals rules.

However, after the Black Box was revised one more time as The Classic Dungeons & Dragons Game (1994), all support for the line ended. After 22 years (or 19 if you prefer), Basic D&D was finally dead.

About the Creators. Though lots of people worked on the Rules Cyclopedia, the two most notable creators are Frank Mentzer, who wrote all the original boxes, and Aaron Allston, who led the Cyclopedia project. Mentzer had left TSR for New Infinities back in 1986, which was likely why he wasn't directly involved in this project. Allston didn't work for TSR at all, but instead had been a freelance RPG writer since 1983. Though he only tended to write one or two books for TSR each year, by the early 90s he was writing the biggest releases for Basic D&D, including the Hollow World Campaign Setting, the D&D Rules Cyclopedia, and Wrath of the Immortals.

I know as soon as I pull the trigger on this it will become available as a POD and I'll still have to pay full price on it.

Any news about when this will get a POD release ? Have an old PDF but really want it in print for the gaming table.

Incredibly unlikely. If WotC wanted to re-release it in print, they'd just print it like they did with the anniversary editions of AD&D, D&D3, etc.

Many years ago, I bought a PDF of this from somewhere -- I have a vague memory of Wizards selling some of them directly. It's about an 80MB PDF. Is this one of substantially better quality, to justify my re-purchasing a book I already own?

The file size for this one is 164.18 MB (see the upper right sidebar). I do know that they have rescanned and/or cleaned up many of the originally offered PDFs, so your chances sound good. But it really depends on how much you use it, and if you had any issues with the version you had.

Hi all,

I have an older version of the Cyclopedia - probably close to 10 years old and about 18mb. How different is this new version? Is it worth getting the newer version? How well does it it print? Has anyone tried to get this printed - such as LULU?

165 MB? Really? That's the best we can do on this?

Hi jason N,

This is the best so far that we can get from an old book scanned for digital consumption. You don't, of course, expect a great quality in a retina display ipad.

I was told that there is indeed a version that has bookmarks and such, sold at the same price on RPGNow, but this one does not.

Im looking at it right now, and it is indeed bookmarked by chapter and sub-chapter sections. Not only that, the text is selectable and can be copy/pasted & searched.
The file size is a bit big, but overall what I'm seeing here is a pretty good quality.

Bruce H February 14, 2015 6:29 pm UTC
No idea what happened. I re-downloaded and the file is ok now, though a bit too fuzzy for my taste. But the bookmarks are ok.

This PDF doesn't appear to have any bookmarks and seems of poor quality. It's hardly worth the few dollars to purchase it.

Ronald C February 13, 2015 2:36 pm UTC
I agree. No errata incorporated, either. It's just a mediocre quality scan of the book. Nostalgia cash-grab.

The PDF does indeed have bookmarks and the scan looks really clean to my eyes. I purchased one of the older scans of this years ago before they were pulled from availability, and the contrast in the quality of scans is stark.

What are you talking about? There are bookmarks, quite clearly. And while the file size is pretty huge, it still displays quite well across all my devices.

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
