Invisible Cities

Italo Calvino

Lent in 2023 to someone whose name arrives slowly. The notes on the copy say who it was, which is more than you can.

Seven cards, filed in order

  1. Card 015 sec

    Scan the ISBN

    Point the phone at the barcode, type the ISBN, or search by author and title. Author, title, year, binding, language and cover fill in from Open Library, and you check them before saving.

  2. Card 0230 sec

    Name the copy, not the title

    Then the edition and the printing from the copyright page, so a first printing and a book club reissue are two cards rather than one.

  3. Card 0310 sec

    Grade it on the trade's scale

    As new down to Poor, the words a dealer uses, explained further down. The same grade means the same thing on every card.

  4. Card 041 min

    Photograph the jacket and the flaws

    Up to five photographs a copy: jacket, spine, the price on the flap, the inscription. Dated evidence, taken before a loss rather than after it.

  5. Card 052 min

    Bring the old list

    Upload the spreadsheet you already keep as a CSV and match its columns to the fields. Each row becomes a card.

  6. Card 061 link

    Lend a list, not the books

    A read-only link to one collection, all your books or the whole account, for a friend or a reading group. What you paid stays off it, and the link stops working when you remove it.

  7. Card 071 click

    Print the shelf, or take it with you

    Every copy in a collection, its condition, what you paid and a photo, as one PDF for an insurer or a police report. Or a CSV of every field, or a zip of the whole account with the original photographs.

The trade's ladder, plainly

One grade a copy, jacket included

Very good

Read and kept well. Slight wear at the edges, a little rubbing to the jacket, no tears, the text clean throughout.

Colophon

Why we built it

The shelves stop being a library at around four hundred books. After that they are a storage system nobody documented: two copies of the same novel in different translations, a paperback you are certain you lent to someone whose name will not come, and a signed first that is worth eleven times what you paid and is currently holding up a plant.

A title is not a copy. First printing or fourth, jacket or none, price-clipped or not, inscribed to you or to a stranger in 1971 — these are the differences between a book worth twelve and the same book worth twelve hundred. A list of titles is the one thing that cannot tell you which you have.

So stashu catalogues copies. Author and title, the edition and the year it was printed, the ISBN where there is one, a grade on the trade's scale, photographs of the jacket and the inscription, what you paid and when, and the collection it belongs to.

Then, when a pipe bursts or a flat is emptied, it prints the whole shelf as a document an adjuster can work from. No feed, no followers, no reading challenge — just an accurate, private, faintly obsessive account of the stacks.
