I settled on using Zotero (meant for academia, but whatever, it does what I need) for cataloguing/organizing my ttrpg pdf hoard and I'm trying to set up some top-level tags to make it a bit easier to sift through what I'm looking for. One set of tags will be genre tags (fantasy, sci-fi, horror, etc), with another level below that for sub-genre (cyberpunk, supernatural, low fantasy, post-apocalyptic, etc).
Another set of top-level tags will focus on the actual types of books/products one might see for an RPG. These are just all the terms I've come across before, setup in a hierarchy that makes sense to me, though sometimes terms aren't used consistently across different RPG lines. Since some products can straddle multiple genres/categories, I'm hoping tags will help make it easier to sort through everything. Does this set of categories/sub-categories make sense? I'm still at the early stages of just importing everything into a library, so I'm sure there's categories I've not thought of or considered.
- Core Rulebook (books required to play)
- Player Handbook (this might straddle the line between core and supplement)
- Supplement (books that expand the rules/setting)
- Sourcebook
- Bestiary
- Splatbook
- Adventure/Scenario/Module
- Setting
- Accessory (mostly non-book related items)
- Cards
- Maps
- Fiction
- Music/Audio
- Screens
- Sheets
- Character sheet
- Rules/Cheat sheet
- Misc sheet
- Resource (more for general books on RPGs, system-agnostic)
- GM aid
- Player aid
- Educational
- Tables
I would have the top level tag "Rulebook" and put "Core Rulebook" as a sub-tag. Under Rulebook also have "Player Handbook", "GM handbook" and "Splatbook". Keep the rules together.
Also tags for your dominant systems (ex DnD, PbtA) including "System Agnostic". Perhaps add subtags "Pre-made" and "Generators" under "Setting". Publisher tags? Language? Decade/year of release? Have played?
