Find the major sections
Most modern checklists divide the product into base cards, insert sets, autograph programs, sketches, and specialty or one-of-one categories. Read the headings first before searching for a character name.
A character can appear in several sections with different card codes and rarity structures.
Separate card identity from parallel
The card number or code identifies the underlying design. A parallel is a version of that card. Store them as separate fields so the same card can be tracked across several finishes.
This is the structure used in the IDS Card Archive.
Watch for section-level parallel lists
A checklist may list a parallel ladder once beneath a set heading rather than repeating it beside every subject. That means the listed finishes apply to the cards in that section unless the document says otherwise.
Do not assume every parallel in the product applies to every insert or autograph subset.
Understand autograph and sketch lists
Autograph checklists may use signer names, character names, card codes, or combinations of all three. Sketch checklists often list artists rather than individual finished artworks.
Treat artist lists as program references, not as conventional card-number checklists.
Version control matters
Manufacturers can revise checklists. Save the version or date of the checklist you used, and update your records when a newer official document resolves a discrepancy.
