Long out of print! I've got what I think are the few remaining new copies. About 8 years ago Paul sent a case to the EAA for sale in their museum shop and I heard that Aircraft Spruce had some for sale. Possibly obtained in a swap with EAA. You also see them on Ebay occasionally. The better book was "This & That About The Ercoupe". About 5 years ago I spoke to Paul about the rights to reprint it, but alas the photos were all gone. I suppose it could be recreated using new photos, but that would be a chore I'm not up to, nor do I think I could get his permission.
