I sort them by certain types and then by name.
Within each monster, I add a shortcut text that links to a text. E.g. [CR] for Critter Compendium. Within the Tag Domains I setup the various books and set them on automatic. I hope that one day these links will be found automatically.
Right now an additional scan via the wrench clear and add content tags is necessary.
Alternatively I just add a normal tag.
Also I begun to add a TOC for each book which have been added as Source topics. From there the topics will link to each book as well.
Still to decide which method works best.
Auto Accepting snippet tags would be the best
