Over on the ENWorld Forums ^[1] “MongooseMatt” has offered up a huge amount of the Mongoose Publishing d20 catalog for a free wiki project…

We produced a great deal of OGC under D20. Most of these books are now out of print, with just PDF copies available – by the end of the year these will disappear too, as it is not realistic for us to remove D20 licensing off every product we produced over the years. Just too many!

However, it seems a shame to have all this material simply disappear, so. . .

If there is any interest, we would be prepared to make the vast majority of our D20-based content available freely. In the past, there has been talk about an OGC Wiki of sorts, and I think we can kick such a project off in a sizeable way.

That is very cool of them to offer. As to actual content:

This would include all the Quintessentials, Slayer’s Guides, Encyclopaedias, Ultimates – potentially, even some Babylon 5 material, if someone is prepared to remove all the licensed text (no Conan though, as that is still current!)

Volunteers have already signed up and it appears the task is underway. It also looks like a couple of other publishers have signed up as well. As noted, however, most of the art and flavor text will be stripped out of these books, so if you are looking to complete your collection before these products are pulled, drop by the Flames Rising RPGNow Shop ^[2] and scoop them up.
