This document discusses ways that libraries and archives can rediscover, reinterpret, and share hidden treasures in their collections. It encourages defining collections through subject headings, keywords and controlled vocabularies. Business records and scrapbooks could become archival or local history collections. Published materials like rare books, artists' books, local authors could be rediscovered through reformatting and sharing digital content online. Photographs, oral histories and additional acquired collections could add to an organization's hidden treasures. Contact information is provided for preservation services.
