What is Periodicals Index Online (PIO)?
Periodicals Index Online is an index to articles from thousands of journals within the arts, humanities and social sciences covering the period 1665-1995.
Provides access to the contents pages for every issue of over 7,000 journals, from their inception to 1995, and includes separate records for over 20 million journal articles, across 37 key subject areas and 58 languages and dialects.
Periodicals Index Online began as a collaboration with Harvard University Library in 1991 and it’s now the largest index in the humanities and social sciences.
Use Periodicals Index Online to help you:

- Search a vast – and growing – number of article citations. Nearly 21 million index records are currently available and around 800,000 are added each year.
- Find international and multi-disciplinary research, with 37 subject areas covered and 58 languages and dialects represented.
- Discover older journal content not included in other indexes. PIO has a deep chronological coverage going back over 300 years

- Cross-search PIO with Periodicals Archive Online (PAO) or any other historical or current content available in the ProQuest platform, such as newspapers, dissertations, full text articles, bibliographical databases, etc.
