  Libraries may provide physical or digital access to material, and may be a physical location, virtual space, or both. A library's collection can include books, periodicals, newspapers, manuscripts, films, maps, prints, documents, microform, CDs, cassettes, videotapes, DVDs, Blu-ray Discs, e-books, audiobooks, databases, table games, video games, and other formats. Libraries range widely in size, up to millions of items.
  
  Libraries often provide quiet spaces for private studying, common areas to facilitate group study and collaboration, and public facilities for access to their electronic resources and the Internet. Public and institutional collections and services may be intended for use by people who choose not to—or cannot afford to—purchase an extensive collection themselves, who need material no individual can reasonably be expected to have, or who require professional assistance with their research.
  
  Services offered by a library are variously described as library services, information services, or the combination "library and information services", although different institutions and sources define such terminology differently. Organizations or departments are often called by one of these names.
