Rules
NEVER recommend a specific software product or platform for inventory management -- provide schema and workflow that work in any system (spreadsheet, database, paper)
ALWAYS include the universal fields in every inventory schema regardless of collection type
Condition grading must use a defined scale with written criteria for each grade -- never just "condition: good" without defining what "good" means
Storage recommendations must include environmental controls (temperature, humidity, light) appropriate to the collection type
Protective housing recommendations must be specific to the material type -- PVC holders damage certain collectibles; acid-free materials are mandatory for paper-based collections
The cataloguing workflow must include photography as the first step -- visual documentation prevents disputes about condition at time of acquisition
ALWAYS include a backup procedure in the maintenance schedule
Item IDs must be unique and follow a consistent format -- recommend a type prefix plus sequential number
On-disposal procedures must archive the record, not delete it -- historical records of items that were in the collection have value for provenance and tax documentation
If the collection exceeds 200 items, recommend batch cataloguing (process 10-20 items per session) rather than attempting the entire collection at once
Edge Cases
User has an inherited collection they know nothing about: Start with a triage process before full cataloguing. Sort items into broad categories first (type, apparent age, apparent condition). Photograph everything in batches. Do not assign detailed grades until the user has basic familiarity with the category. Recommend a reference guide or collector community for the specific type. Full cataloguing can follow once the collection scope is understood.
User has a very large collection (over 1000 items): Recommend a phased approach: catalogue the most valuable or fragile 10% first, then systematically work through the remainder at a sustainable pace (10-20 items per session, 2-3 sessions per week). Estimate total cataloguing time: approximately 5-10 minutes per item for detailed cataloguing, 2-3 minutes per item for basic entry.
User collects across multiple categories (e.g., stamps and coins and cards): Create a unified inventory system with a master table and type-specific extension tables. The master table contains universal fields; each type table contains type-specific fields. Link via item ID. This avoids blank columns for irrelevant fields while maintaining one searchable inventory.
User wants to catalogue for insurance purposes: Emphasize documentation of acquisition cost or current estimated replacement value. Photographs must be high-resolution and stored separately from the collection (cloud backup or safety deposit box). The inventory should be exportable as a document that an insurance adjuster can use. Recommend updating estimated values annually for high-value items.
User has items that are damaged or in poor condition: Still catalogue them -- completeness matters for the collection record. Grade accurately using the scale (Fair or Poor is a legitimate grade). Note specific damage in the defects field. These items may still have value for completeness in a set or as candidates for professional restoration.
Example
Input: "I have about 150 vinyl records that I've collected over the years. They're all in a closet in various conditions. I want to organize them properly and know what I have. Some might be worth something but mostly I just want to take better care of them."

Nearly flawless. May have been played but shows no wear
Minimal handling. No splits, ring wear, or writing
Very Good Plus
VG+
Light surface marks visible. Plays with very minor noise
Light wear at edges. No splits. Minor ring wear acceptable
Very Good
VG
Audible surface noise, light scratches. Still enjoyable to play
Obvious wear: ring wear, minor seam splits, light writing
Good
G
Significant surface noise and scratches. Plays through without skipping
Heavy wear: seam splits, writing, tape, missing pieces
Fair
F
Plays but with skips or repeating grooves
Major damage: tears, water damage, missing panels
Poor
P
May not play. Cracked, warped, or deeply scratched
Barely holding together or missing entirely
Important: Disc and sleeve are graded separately. A VG+ disc in a G sleeve is common for older records.
Cataloguing Workflow for Vinyl Records
Photograph the front cover, back cover, and record labels (both sides)
Record the catalog number from the spine or label
Check the dead wax (the smooth area near the label) for matrix numbers
Grade the disc: hold at an angle under light -- look for scratches, scuffs, and warping
Grade the sleeve: check seams, ring wear, corner wear, writing
Enter all fields in your inventory spreadsheet
Place the record in a new inner sleeve and outer sleeve if the originals are damaged
File in alphabetical order by artist in the designated storage location
Update the storage_location field with the final position

Storage rules for vinyl:
Store vertically, never stacked flat (stacking causes warping)
Maintain 65-72F temperature (avoid attics, garages, and basements with moisture)
Keep humidity at 40-55% -- vinyl and cardboard both suffer in high humidity
Avoid direct sunlight on any shelf or crate
Do not overstuff crates -- records should slide in and out without friction

Establish condition grading framework. Define a grading scale appropriate to the collection:
Generic grading scale (for collections without established industry standards):
Mint (M): Flawless, as-new condition. No wear, damage, or aging visible
Near Mint (NM): Almost perfect. Only the most minor imperfections visible under close inspection
Excellent (EX): Minor wear visible. All original parts/components intact. No significant defects
Very Good (VG): Moderate wear visible. All original parts present. Minor defects acceptable
Good (G): Noticeable wear. May have minor missing elements. Clearly used but intact
Fair (F): Significant wear or damage. May be missing elements. Structural integrity maintained
Poor (P): Heavy wear, damage, or missing components. Primarily of interest for completeness
Industry-specific scales (use these when applicable):
Coins: Sheldon scale 1-70 (Poor-1 to Mint State-70) or descriptive (Good, Fine, Extremely Fine, Uncirculated)
Comics: CGC/CBCS 0.5-10.0 scale or descriptive equivalent
Trading cards: PSA/BGS 1-10 scale
Stamps: Mint/Unused/Used with subcategories (Original Gum, Hinged, No Gum, Canceled)
Grading documentation: For each item, record:
Grade assigned
Grader: self-graded or professionally graded (service name and certificate number)
Date graded
Specific defects noted (list each defect)
Build the cataloguing workflow. Define the step-by-step process for adding new items:
Step 1: Receive and document. Photograph the item upon acquisition (front, back, any notable features or defects). Record acquisition date and source immediately.
Step 2: Research and classify. Identify the item using reference materials. Determine category, year, variety, and any special characteristics. Assign to the correct classification within the collection.
Step 3: Grade condition. Using the appropriate grading framework, assign a condition grade. Photograph any defects. Note the specific factors that determined the grade.
Step 4: Assign ID and enter data. Generate or assign the item ID. Enter all fields into the inventory system. Attach photographs.
Step 5: Store and label. Place the item in its designated storage location. If using physical storage, label the storage container with the item ID. Update the storage location field.
Step 6: Backup. Ensure the inventory data is backed up (cloud storage, second copy, or export to spreadsheet).
Design storage documentation. Create a storage map:
Quarterly: Spot-check 10% of stored items against inventory records. Verify storage conditions
Annually: Full inventory audit -- verify every item against the database. Update condition grades for any items showing change. Review storage supplies and replace worn protective housing
On acquisition: Follow the cataloguing workflow for every new item within 7 days of acquisition
On disposal: Mark items as sold, traded, or donated. Record sale price and date. Archive the entry (do not delete)
