The early monographs had the appearance of being printed on a laser printer with black tape on the spine.

They changed that approximately 18 months or so ago and now issue them in perfect bound format.

Monographs are only sold through the Chaosium web site and are small print runs. They pay the author for the rights to publish up to 500 copies and have small batches of them done up as print-on-demand batches.

The author is paid $250.00 for the monograph and if the book sells well enough there is a chance that Chaosium will pick it up as a full book to be distributed through stores. That has happened with their Mysteries of Morocco which will be released shortly as a full version.

Secrets of Morocco

I have heard from Chaosium and others that there are a few more on the way.

It incorporated much of the 1920's sourcebook and had several color plates.

There was a ton of them printed so it is certainly not scarce but in near-mint it may sell on eBay for $25-$35 depending on the number of bidders it attracts.

It is the best looking core book I've seen. The pages have the parchment feel, and in general it has the old style rulebook flavor while the newer ones are a trifle bland.
