The meticulously edited publication (in i ve copies) contains sixty thousand catalogue numbers of books that were never borrowed from the library in Gdańsk. On certain pages, the catalogue numbers form patterns on which we recognise blurry rasterised pictures of the interiors of the library in question. Rows of books, rows of bookshelves, long alleys of shelves and their storeys; the ‘phantom’ library with its vast expanse of books is depicted by a precise pattern woven from that which – although it has been catalogued – vanishes in the abyss of library collections’ memory.
