Keeping a catalogue raisonne from the start: the tool that professionalises instantly

01What a catalogue raisonne is and why it matters

A catalogue raisonne is a systematic and exhaustive inventory of an artist's oeuvre. For each piece, it gathers essential information: title, creation date, technique, dimensions, support, condition, current location, exhibition history, bibliography, and complete provenance from the moment it left the studio. In its most complete form, a catalogue raisonne is a reference document that accompanies the artist throughout their career and, after their death, becomes the indispensable tool for art historians, dealers and auction houses.

Art historian Sylvie Ramond, who directed the Musee des Beaux-Arts de Lyon, has often emphasised that the absence of a catalogue raisonne is the principal obstacle to serious study of an artist. Without a reliable inventory, it is impossible to distinguish authentic works from copies, to trace periods of creation, to establish links between pieces. The catalogue raisonne is the backbone of an artist's legitimacy on the market.

For a living artist, the catalogue raisonne serves more immediate functions. It lets you know exactly where your production stands. How many works you created this year, how many you sold, how many are on consignment in galleries, how many are in storage in your studio. This information is essential for managing your career strategically. An artist who does not know the state of their stock cannot plan production, adjust prices, or negotiate with galleries from a position of knowledge. The catalogue raisonne transforms intuition into concrete data and blind decisions into informed choices.

02How to structure your catalogue from the start

You do not need sophisticated software to begin. A well-organised spreadsheet suffices at the outset. Each work occupies a row, and columns contain standardised information. The numbering system is the first element to put in place. The most common method uses the year of creation followed by a sequential number: 2026-001, 2026-002, and so on. This system is simple, chronological and allows new works to be added without modifying existing numbering.

Artist Gerhard Richter has maintained a catalogue of his works since the beginning of his career in the 1960s. His catalogue raisonne, which today counts more than 3,500 entries, is a model of rigour any artist can adapt to their own scale. Richter assigns a number to each work as it leaves the studio, records its dimensions and technique, and photographically documents the work in its initial state. This systematic work has allowed him to maintain total control over his oeuvre, quickly identify fakes circulating on the market, and provide institutions with the information they need to exhibit and publish his work.

The minimum information to record for each work is as follows. A unique inventory number. The title, or "untitled" with a short description. The creation date, at least the year, preferably the month. The technique and materials used. Dimensions in centimetres, height by width, and depth if necessary. A photograph of the work, front view, and if possible back and detail. Current status: in studio, in gallery, sold, on loan, destroyed. The buyer's or institution's name if the work has been sold or donated. The sale price if the work was sold. The exhibition history of exhibitions in which the work appeared. Publications in which the work was reproduced.

03Photography, the catalogue's pillar

Photographic documentation is the most important element of the catalogue after the inventory number. An unphotographed work is a work that does not exist in the catalogue. And a poor-quality photograph is almost as useless as no photograph at all. You do not need a professional photographer for every piece, but you must establish a consistent shooting protocol that guarantees constant quality.

Artist Louise Bourgeois systematically documented her works throughout her career. Her archive collection, held by the Easton Foundation, contains thousands of photographs tracing the evolution of each piece from studio to exhibition. This documentation was not the caprice of a meticulous artist. It was a working tool that allowed Bourgeois and her galleries to respond rapidly to any request for loan, reproduction or authenticity verification.

To photograph your works correctly, work in diffused natural light or with two light sources placed at 45 degrees to the work to avoid reflections and cast shadows. Use a neutral background, white or grey. Position the camera perpendicular to the work to avoid perspective distortion. Include a colour scale and a ruler in at least one shot to allow precise calibration. Save your files in high resolution and keep them in a reliable backup system, ideally both on a physical hard drive and in online storage. This dual backup is essential: if your hard drive fails or your studio suffers an incident, your photos still exist somewhere.

04The catalogue as a negotiation tool

When you present your catalogue to a dealer, you are not merely showing your works. You are showing that you are organised, that you have an overview of your production, that you know where your pieces are and in what condition. This level of professionalism enormously facilitates the commercial relationship. The dealer representing you can quickly access the information they need: exact dimensions for a collector with a specific wall, exhibition history for a curator preparing a catalogue, provenance for an auction house requiring verification.

Collectors also appreciate a catalogue raisonne. When they buy one of your works, they receive a certificate of authenticity accompanied by the catalogue number. This document increases the perceived value of the work because it situates it within a coherent and documented body. The collector knows that if they resell the work one day, the existence of a catalogue raisonne will facilitate authenticity verification and value determination.

Artist On Kawara kept a meticulous catalogue of his "date paintings," canvases that simply bear the date of their creation. For each piece, he preserved the day's newspaper in an archive box. This documentary rigour contributed to making these apparently simple works extremely sought-after collectibles, because each piece comes with a documentary apparatus that makes it unique and verifiable. At your scale, the same principle applies: a documented work has more value than an orphaned work whose history nobody can trace.

05Moving from spreadsheet to professional system

As your production grows, the spreadsheet will show its limits. Collection management software such as ArtBase, Artlogic or FileMaker Pro adapted for art are more robust tools that allow you to associate images with records, generate reports, track loans and consignments, and export data for publications or exhibition catalogues. These tools represent a modest investment relative to the value they bring in terms of organisation and credibility.

Some artists opt for a middle ground: a Notion or Airtable database that offers more flexibility than a standard spreadsheet while remaining accessible and inexpensive. The essential thing is not the tool but the discipline. A rigorously updated spreadsheet is infinitely more useful than sophisticated software left neglected. The key is building a habit: every time a work leaves your studio, whether for a sale, loan, exhibition or gift, you update its status in the catalogue. Every time a new work is finished, you assign it a number and complete its record. This reflex, once established, takes only a few minutes per work and saves you hours of retrospective work when a dealer asks for a complete inventory.

06The catalogue as a mirror of your practice

There is something deeply satisfying about seeing the entirety of your oeuvre organised, numbered, documented. The catalogue raisonne is not merely an administrative tool. It is also a mirror of your practice. It allows you to step back from your production, to identify series, ruptures, evolutions, prolific periods and moments of transition. This overview feeds your reflection on your own work and helps you make informed decisions about the direction of your practice.

On Artedusa, the rigour of your catalogue is directly reflected in the quality of your artist page. Each work presented with its complete information, dimensions, technique, date, catalogue number, gives potential collectors the confidence they need to consider a purchase. An artist whose page is a precise and well-documented inventory inspires more trust than one whose work entries are incomplete and approximate. The catalogue raisonne is the least visible but most profitable investment an artist can make in their career.
