Yes, the Craftsman's Manual is from Requiem. If the game crashes the instant you try to read the book, it is looking for the Inventory Mesh and not finding it. By default, Requem puts that mesh and its texture in the correct place but it is possible that a Compatibility Patch is out of date or has a mistake in it. To start off diagnosing this, check that you are using the correct version of Requiem and have any appropriate patches for your mods up to date too. If you are sure that you have the correct patches and have installed the mod properly, go over to the Requiem mod on the Nexus and ask for help there. If you are familiar with TES5EDIT, you can tell it to Load All plugins, go to the Requiem.esp, look in the BOOK section for the Craftsman's Manual and see if any other mods apart from Requiem are editing that record.
