The Summon search box is the orange search box located on the RIT Libraries' homepage. Summon allows you to search almost all of the library's content from a single search box similar to a Google search. A Summon search will typically deliver many results. The key to success is to utilize the filters located in the margin to the left of your Summon search results.
You can easily locate e-books using the refinement filters within Summon. Conduct your Summon search, refine your search to "items with full text online" and limit the content type to "Books/ebook". Your list of results will now be only e-books.
These databases are good for general background about WWII, eugenics, and the Holocaust. If you expand your search to use the term disability and WWII, you will have more success, as there are few sources related to the Deaf population.
Rogow, Sally M. "Child Victims in Nazi Germany." The Journal of Holocaust Education 8.3 (Winter 1999): 7187.
During the Nazi years, thousands of non Jewish German children were victims of unrelenting persecution and genocide. Children who were blind, deaf, physically disabled or mentally handicapped,orphans, juvenile delinquents and adolescent nonconformists were removed from their homes and communities, isolated in institutions and work camps and many thousands were murdered. Significant members of the medical profession found it personally and professionally profitableto engage in murder and gave it a protective veneer of respectability. In the process Europe's mostadvanced and comprehensive system of rehabilitative education was destroyed. This article, entirely based on secondary literature, provides a concise synthesis of this history for teachers.
