Sub-collections
Collections can now be organised into smaller sub-collections, giving you another level of structure without forcing everything into separate top-level collections.
Product Update · September 2026
Collections that fit what you collect
Collectaneum now gives you more freedom to organise collections within collections and capture information that is specific to the things you collect.
Why this changed
Not every collection fits the same shape
A collection can become complicated long before it becomes large. One collector may organise around a single product line, while another may want to separate periods, themes, manufacturers, artists, series, campaigns, or entirely different areas of interest.
The information that matters also changes between collecting domains. Rather than trying to make every collectible fit one universal set of fields, Collectaneum can now preserve a common Registry structure while allowing specialist detail where it is genuinely useful.
What's new
More flexibility without losing structure
Organise around your collection
Sub-collections can reflect the way you actually think about what you own — whether that means a particular series, period, theme, manufacturer, campaign, artist, range, or another grouping that matters to you.
Custom fields by domain
Collecting domains can now have their own custom fields, allowing records to capture information that matters within that area without adding irrelevant fields everywhere else.
Keep specialist detail where it belongs
A field that is important for one type of collectible may be meaningless for another. Domain-specific fields let Collectaneum accommodate specialist information while keeping the wider Registry coherent.
Sub-collections
Structure inside a collection
Until now, the main organisational boundary in the Registry was the collection itself. That works well at the top level, but it can become restrictive when a collecting area develops its own natural groups.
Sub-collections add that missing layer. You can keep a collecting area together while still giving meaningful groups within it their own identity, rather than creating additional top-level collections simply to organise your records.
Custom fields
Different collectibles need different information
Collecting terminology is rarely universal. The details that help identify, describe, compare, or document an item in one domain can be completely different from those that matter in another.
Domain-specific custom fields provide a place for that information without expanding every owned-item record with fields that most collectors will never use. The common Registry stays consistent; the specialist layer can adapt to the subject.
What you need to do
Nothing
Existing collections and owned-item records remain in place. Sub-collections and domain-specific fields simply give you additional ways to structure and describe them where useful.
The principle behind the update
Structure should provide consistency without assuming that every collector, every collection, and every collecting domain needs to describe things in exactly the same way.
