Looking for a research or white paper, conference proceeding, pre-print, or report but can’t find a copy in your library’s catalog or popular search engines? Check out the new Internet Archive Scholar search index from the Internet Archive. 
According to the Internet Archive Blogs, Internet Archive Scholar indexes over 25 million research articles and other scholarly documents preserved in the Internet Archive spanning from the eighteenth century to the present. It includes content from the natural sciences, humanities, biomedicine, art, history, industrial research, government reports, and more.
Content in this search index comes in one of three forms:
- public web content as preserved in The Wayback Machine and Archive-It partner collections
- digitized print materials from paper and microform collections
- general materials from archive.org collections, including collaborations with partners
A link to the full-text work is provided when possible. In other cases, depending on search filters, results are included for which there is only a bibliographic catalog entry. It may still be possible to obtain access through a public library or from the publisher directly.
For more information and tips on advanced searching, see the user guide. Hat tip to beSpacific.
