The Libraries' Special Collections Research Center (SCRC) houses several Philadelphia newspaper "clippings collections," including the George D. McDowell Philadelphia Evening Bulletin Newspaper Collection.
Temple Libraries provide online access to many Pennsylvania newspapers through databases such as Global Newsstream (formerly ProQuest Newsstand). Please use Journal Finder to determine the availability of particular Pennsylvania newspaper titles.
A digitized scan of the last ninety day of The Philadelphia Inquirer is available through the database Library PressDisplay. It's just like reading the printed paper, only online! From the PressDisplay homepage, select Titles by Country / USA / The Philadelphia Inquirer. To find back issues, click on the thumbnail for today's paper, then use the dropdown calendar above the display of today's paper.
