Articles from American Periodicals from the Center for Research Libraries (APCRL) are now indexed in the latest release of C19: The Nineteenth Century Index, available from ProQuest. C19 Index is a useful tool for discovering 19th-century books, periodicals, official documents, and newspapers; it now includes more than 600,000 entries from 25,000 issues in over 150 titles from APCRL’s growing content. Subscribers to APCRL can link from the index entries directly to full text. Patrons at all CRL libraries have digital interlibrary loan access upon request to articles, issues, and volumes converted for APCRL.

The trade, literary, and scientific journals from CRL’s collections scanned in full color with searchable text for APCRL span the 19th and early 20th centuries. This historical collection illustrates the growth of American influence on business, industry, and culture. CRL launched the APCRL project in 2009 in collaboration with ProQuest.
