Trilogy Manual

The Trilogy Manual came with the release of the Ultima Trilogy I II III and the Ultima I-VI Series. The book is 100 pages long and essentially a compilation of The First Age of Darkness, The Second Age of Darkness, The Book of Play, The Ancient Liturgy of Truth and The Book of Amber Runes.

Description
However, not all of the information and illustrations had been taken over into it, since the number of pages had been capped at 100. This is especially noticeable in the Ultima III manuals, which are missing several illustrations and all page borders (which are missing from the Ultima I manual as well). Yet, some new illustrations were made, especially for the spells of Ultima III. Also, some of the title covers had been lost with the book. The section for Ultima II essentially is a complete rewrite of the original manual in order to get the narrative straight and remove lots of highly dated slang, which had run rampant in the original 1982 manual. It in the process gained a new cover picture.

Other Editions
The book did get translated into Chinese (Taiwan), Korean and Japanese for the respective releases of the compilation. While content-wise they are all equal to the original, only the Chinese version has the original cover. The other two versions have widely different covers. The Japanese edition also changed the layout and interiors of the book significantly.
