Catalogue a metal vinyl collection

A coloured vinyl and a black vinyl of the same album are different objects if you care which one you have. Say so in the notes: the colour, the pressing, the edition. Future you will not remember it from the album title alone.

Inserts and posters go missing. A note that the poster is there, or is not, saves an argument with your future self, and it is the detail a buyer will ask about. Write it while the sleeve is open.

Catalogue the copy you own. Colours you do not own are not part of the shelf, even if you like the idea of them. They belong on the wishlist, one variant at a time, if you are actually hunting them.

Pick the pressing that matches when you add the record, so the guide, if there is one, refers to that release. A picture disc or a limited colour can sell differently from the ordinary black vinyl. If you care, type your own price. Do not let a guide for a different edition stand in silently.

A photo of your sleeve helps when two editions look similar in a list. Upload it if the saved artwork does not show the variant. A placeholder is better than the wrong cover.

Add the record, write the colour or edition in the notes, and type the price you paid if you know it. Two copies you own are two rows. A colour you want is a wishlist line.

Condition notes still matter. A limited pressing with a seam split is not the same object as a mint one, and the guide has not looked at yours.
