What's Inside?

Return to the Corbitt House!

Call of Cthulhu 1st-6th edition included the scenario The Haunting in the core rulebook. However for 7th edition this scenario, in which the players are recruited to investigate a supposedly haunted house in 1920s Boston, instead featured in the Call of Cthulhu Quick Start rules. But because The Haunting has been something of a rite of passage for untold thousands of Call of Cthulhu players since its debut in 1981 we decided it was fitting to put that scenario back into the 40th Anniversary Keeper Rulebook. You'll find it here, along with the two scenarios already included, Amid the Ancient Trees and Crimson Letters.

This looks gorgeous, and as an aspiring GM who only has the Quick Start my eyes lit up! The bottom of this page shows a mock up of a hardcover book; are there plans to produce those or do you recommend any 1-off printers?

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.
