Start in OASys, by running a Title search for the title of the newspaper. If there are too many irrelevant results, try the advanced or modified search and add the Subject search "newspapers" along with your other search term. Depending on the newspaper, we may have indexed access through an online database, which mean you can search across the text of entire articles, and easily locate the specific article you are looking for.
If we don't have access to an index, you'll probably have to mark the date of the article, and find the print or microform version of the paper:
If there are no Oxy results or no electronic holdings, try CRL, the Center for Research Libraries. As a member of this group, Oxy gets quick access to materials held in their collections. Once you find the title and date you are looking for, check for digital access through CRL, or order it through an ILL request. Though some ILL requests can take a long time, our membership in CRL means we'll get these materials faster.
Unlike journal articles, many older newspapers are only available in microform. Microform comes in 2 formats: Film (rolls of film) and Fiche (flat rectangular transparencies). Using WorldCat or CRL you can find a variety of obscure news sources. Once located, you need to request these materials through Interlibrary Loan (ILL). This will most likely be in microform format. Once arrived you can read, print and save pdf files from the news source, using the microform reader located next to the second printer in corner of the 2nd floor main library area.
