Primary sources are materials produced by participants or observers at the time of an event or during a particular span of years. They are "original" in that the recording of the event or experience originates with the participants or direct observers. Some examples of primary sources are:
Secondary sources are materials that interpret, analyze, describe, or explain primary sources. Textbooks, encyclopedias, biographies, and journal articles are examples of secondary sources. These sources are "secondary" in that usually they are one step removed from the event about which they comment or analyze. Use catalogs and databases to find secondary source books and articles. These sources will build your background knowledge about your topic. Use them to inform yourself about what scholar's say about your topic.

Braceros in Oregon Photographic Collection
Key Subjects for your class
Due to armed forces manpower requirements and competition with higher paying jobs in the defense industries, the early 1940s saw a noticeable decrease in the number of farm workers in the United States. At the same time, farmers were asked to increase production as part of their efforts to support World War II.
In 1942, the United States government signed a labor agreement with Mexico that allowed its male citizens to work as farm laborers throughout the U.S. It was known as the Braceros Program. In Oregon more than 15,000 Mexican men worked on farms in all parts of the state from 1942 through 1947.
The 102 photographs in this collection document the activities of Oregon's Bracero workers, recording their cultivation and harvesting work in the fields and orchards, as well as the farm labor camps in which they lived.
For more information, check out the Extension Service Records (RG 111)
The county extension office annual reports for those counties in which Braceros worked during WWII often include a section on how many workers were utilized in the county and the types of work done. Some of the reports also include narrative on problems that the workers encountered. These reports are on microfilm only.

This is a service provided by RLG, a non-profit organization of libraries, archives, museums, and other cultural institutions. It is a centralized index to archival collections located throughout the world and is a valuable resource for locating records in other archives.
WorldCat is a global network of libraries that unite their collections in one master catalog. It is a union catalog of over 49 million records representing books, journals, dissertations, audio-visual materials, and manuscripts in repositories worldwide.
There are lots of primary source materials in libraries around the country; this catalog holds a growing number of more than 6,000 links to online finding aids. Included in their genealogy search are books, ship passenger lists, historical society records, archival photos, articles on research techniques, family histories, and digital image collections.
National Union Catalog of Manuscript Collections (NUCMC)
The National Union Catalog of Manuscript Collections is a print and online catalog of manuscript collections held in US repositories. The Library of Congress provides a Web interface for searching archival and manuscript cataloging in OCLC WorldCat.
National Inventory of Documentary Sources in the United States (NIDS)
By bringing together thousands of finding aids from libraries and archives across the United States and reproducing them on microfiche with a unified index, NIDS gives users unparalleled access to federal, state, academic and other documentary sources. In allowing researchers to examine actual finding aids, NIDS goes further than either NUCMC or RLIN which offer collection-level descriptions, but do not contain detailed listings of the contents of collections.
This is a current directory of over 5,500 repositories and more than 161,000 collections of primary source material across the United States. NUCMUC & NIDS were folded into this database.
Using ArchivesUSA, researchers are able to read descriptions of a repository's holdings to determine whether a collection contains material useful to their work as well as find the information they need to contact the repository directly. Repository records provide detailed information including phone and fax numbers, hours of service, materials solicited, email and home page URLs when available. Each collection record links to its corresponding repository record, simplifying the research process.
Repositories of Primary Sources
This is a listing of over 5000 websites describing holdings of manuscripts, archives, rare books, historical photographs, and other primary sources for the research scholar. Includes international archives.
The UNESCO Archives Portal gives access to websites of archival institutions around the world. It is also a gateway to resources related to records and archives management and to international co-operation in this area.
Use the LexisNexis Congressional Index to identify congressional publications (hearings, serial set, house/senate reports and documents, etc) from 1789-present. Once identified, then find the full text in print, microfiche, or online depending on availability.

Using the microform machines can be a fun, challenging, and unique experience! And probably unlike anything else you will do in your research adventure.
We have 6 machines, all found on the 3rd floor of The Valley Library. 3 of the machines offer a scanning option, and one is coin operated.
Library staff will be happy to help you, but for who would rather go it alone, we have created a tutorial in Flickr.
There are also instructions posted next to each machine and on the Archives' Microform Guidance page .
There are a number of tutorials on the web, some examples are:
