Deaccessioning is the formal process by which a museum, library, or archive permanently removes an object or item from its collection. It is the institutional equivalent of deciding to sell, transfer, or destroy a holding — and it is among the most contested decisions in collections management. What It Is Accession means to formally add something to a collection. Deaccession is the reverse: the institution decides that a particular item no longer serves its mission, is redundant, is too costly to preserve, or is better held elsewhere — and removes it from the permanent collection through a defined process.

A finding aid is a document that describes the contents, organization, and context of an archival collection. It is the researcher’s map to a body of records — explaining what exists, how it is arranged, and how to request specific materials for examination. What It Is Archives are not libraries. Library materials are individually catalogued: each book has a record, a call number, a discrete identity. Archival collections are processed differently.

A holograph manuscript is a document written entirely in the hand of its author. Every word, every correction, every marginal note is in the author’s own handwriting — no secretary, no copyist, no amanuensis was involved. The term is precise and frequently misused. What It Is In an era before typewriters and word processors, most literary, legal, and official documents were produced through some form of dictation or copying. Authors drafted; scribes transcribed.

Provenance, in archival science, refers to the origin of a body of records — specifically, the person, family, organization, or institution that created or accumulated them. It is the foundational principle of archival arrangement and description, and it is distinct from the art world’s use of the same word. What It Is The principle of provenance — known in French as respect des fonds — holds that records from different creators must be kept separate and not intermingled, even if their subject matter overlaps.

Recto and verso are the two sides of a leaf in a manuscript, book, or document. Recto is the front — the right-hand page in an open book. Verso is the back — the left-hand page. The terms are standard in bibliography, archival description, manuscript studies, and art history, and they appear constantly in catalogue entries and scholarly footnotes. What They Are In Western manuscript and book tradition, leaves (individual sheets) are numbered rather than pages.
