Read full description

Private Collection is a beautifully simple way to catalogue, organise and preserve the information that belongs with your art collection. Designed specifically for private collectors, it brings together artworks, photographs, documents, provenance, acquisition details, valuations, condition records and notes in one private archive — so the story and documentation of each work stays with the artwork. Whether you are recording an established collection or documenting a new acquisition, Private Collection gives you a clear, structured place to keep the information that matters. Your collection, organised Create a visual catalogue of the works you own and quickly browse or search your collection. For each artwork, record details including: • Artist • Title • Year • Medium • Dimensions • Description • Location • Photographs and supporting images Keep documents with the artwork Attach important files directly to each artwork record, including: • Certificates of authenticity • Purchase invoices • Appraisals and valuations • Insurance documents • Condition reports • Conservation and restoration records • Other supporting documentation Instead of keeping important collection records across folders, email inboxes and filing cabinets, everything can remain connected to the work it belongs to. Preserve provenance and acquisition history Build a record of where each artwork came from and how it entered your collection. Record previous ownership, galleries or dealers, acquisition dates, purchase details and supporting documentation. Over time, Private Collection helps preserve a more complete history of each work. Track values, condition and care Maintain valuation records alongside the artwork and keep a history of changes over time. Record condition observations, restoration work, conservation treatments and other notes relating to the ongoing care of a work. Know where your artworks are Record artwork locations so you can keep track of works displayed at home, stored elsewhere, on loan or held in another location. Made for private collectors Private Collection is not a public collection platform or an art marketplace. There are no public collector profiles and no gallery sales tools. Your collection information is kept private, with options designed to help protect, back up and export your records. From a first acquisition to a lifetime collection, Private Collection gives every artwork a proper place — together with the information, documents and history that make it part of your collection.
