After reading the articles which were really informative, I will say archives are collections of materials and artifacts kept and preserved by organizations like universities or historical societies. Archival materials are often unpublished and are preserved for their research value. In general just like prof Nora Almeida mentioned in todays class, that archives are consist of records that have been selected for permanent or long-term preservation on grounds of their enduring cultural, historical, or evidentiary value. Archival records are normally unpublished and almost always unique, unlike books or magazines for which many identical copies. To find the archive materials we can go to archive.gov where you can find national archives and much more. Archives can hold both published and unpublished materials, and those materials can be in any format. Some examples are manuscripts, letters, photographs, moving image and sound materials, artwork, books, diaries, artifacts, and the digital equivalents of all of these things. Materials in an archives are often unique, specialized, or rare objects, meaning very few of them exist in the world, or they are the only ones of their kind. The Rober Moses paper are really great example to show that archives are really important, because i think archives really help us to reconnect us with our history, culture and values.
