What you need before you start

Most of the work is gathering facts. Having them in one place saves you from rechecking the same item several times.

The items themselves. Set them out in groups you already think of, such as by type, era, or where they came from.
Details for each item. Name, where it came from, when you got it, and any marks or numbers on it. A photo of each item helps later.
Condition notes. Any damage, repairs, or missing parts, written down while you can see them.
Paperwork. Receipts, certificates, auction records, or letters that say what an item is worth or where it came from.
A category scheme. Decide how you will group things before you start. Type, era, place, or subject all work. Pick one main way and one backup.
A place to record. A notebook, a spreadsheet, or a cataloging tool. Whatever you pick, use the same one for the whole collection.

Do not write down anything you cannot verify. If a detail is a guess, mark it as a guess so you can check it later.

Step by step

Write a short collection summary. A few sentences: what the collection is, how many items, where they are kept, and why you are cataloging it. You will reuse it for every tool and note.
Pick a category scheme. Choose one main way to group items. Type, era, place, or subject all work. Write down the rule so you can follow it later.
Sort the items into groups. Move items into the groups you picked. If an item fits two groups, put it in the main one and note the other.
Record each item. For every item, write down its name, where it came from, when you got it, and any marks or numbers. Take a photo if you can.
Note the condition. Write down any damage, repairs, or missing parts. Do this while you can see the item, not later from memory.
Attach the paperwork. Link receipts, certificates, or auction records to the item they belong to. If a record is missing, note that it is missing.
Check for gaps. Go through the list and find items with no photo, no source, or no condition note. Write down what is missing for each.
Use a tool if you want one. A cataloging tool can list items and sort them into groups. A screening result is a hint, not a decision. You still decide the categories.
Keep a checklist. Track what has been recorded, on what date, and what is still missing. Mark items that are not part of the collection so they stop cluttering the list.
Recheck once a year. Items change, new ones arrive, and details you guessed at may need confirming.

Tools that can do it

Several kinds of help fit this job. Pick based on how much typing you want to do and whether you also want to talk to a person.

A notebook or spreadsheet. It is where you can record items in your own words. Check whether you can search the list later and whether you can add photos.

A local collector group. Many areas have a group for hobby collectors with members who can walk through cataloging. Check whether they offer free help and whether appointments are needed.

Your own records. Look at receipts, certificates, and auction records you already have. Check whether they are listed in writing and whether they cover every item.

Packing Buddy. You take photos of what goes into a moving box, and AI lists the items and picks the room. ^[1] Each box gets a code like K-03, printed on its label. ^[1] Labels print from a home printer on store-bought Avery 5163 or compatible sheets, or on plain paper you cut out and tape on. ^[1] Scanning a box's QR code with any phone camera opens that box in the browser, no app needed. ^[1] You can search your boxes to find which box an item is in. ^[1] Share links let a partner, friends or movers join by typing their name, with no account needed; the movers link comes with your plan. ^[1] The app and its AI box lists are available in 30 languages. ^[1] Free: 3 test boxes per device without an account; with a free account, 10 boxes, 25 AI reads and up to 4 photos a box. ^[1] Plus costs $12.99 a month or $59 a year for 100 boxes; Pro costs $19.99 a month or $99 a year, with unlimited boxes and Bluetooth printers. ^[1] It runs on phones and in a web browser; Bluetooth printing works only in the phone app, not on the web. ^[1]

Common mistakes to avoid

Starting with the tool. Gather item details and condition notes first. A catalog without facts is just a list of names.
Picking a category scheme after you start. If you change the rule halfway, the list becomes hard to follow. Pick one main way and one backup before you begin.
Guessing at details. Use a document, not memory, for where an item came from and when you got it. Mark guesses so you can check them later.
Skipping condition notes. Damage and repairs are easy to forget. Write them down while you can see the item.
Forgetting the paperwork. Receipts, certificates, and auction records belong to the item. Link them so they are not lost.
Not checking for gaps. Go through the list and find items with no photo, no source, or no condition note. Write down what is missing for each.
Not keeping records. Note dates, names, and reference numbers for every item and every note you add.

Frequently asked questions

How to start cataloging a collection by category?

Start with a short summary of the collection: what it is, how many items, where they are kept, and why you are cataloging it. Pick a category scheme before you start. Sort items into groups, record each item's name, source, and condition, and attach any paperwork. Note what is missing for each item.

What details should be recorded for each item in a collection?

Record the item's name, where it came from, when you got it, and any marks or numbers on it. Take a photo if you can. Write down any damage, repairs, or missing parts while you can see the item. Link receipts, certificates, or auction records to the item they belong to. If a record is missing, note that it is missing.

Does a cataloging tool decide the categories for a collection?

No. A cataloging tool can list items and sort them into groups, but you decide the categories. Packing Buddy lists the items and picks the room. ^[1] You still decide the category scheme and follow it for the whole collection.
