The PERN eLibrary is an important and unique reference tool for classic population-environment literature; journal articles; conference and working papers; relevant data sets; and educational resources. The eLibrary database is annotated and includes bibliographic citation information, Internet links to the materials, and keywords.

For recent, peer reviewed articles from more than 60 journals, check out the Population Environment Collection.

Search expressions may be words or phrases. The contents of the database will be searched for all of the words contained in your expression (implicit 'and' between words) regardless of their order of occurrence. Phrases enclosed in double quotes (e.g., "climate change vulnerability") will return an exact match on the full phrase. Queries are case-insensitive, meaning upper and lower case letters are treated the same. Use the percent sign (%) as a wildcard to match any number of characters (e.g., “method%” returns “method”, “methods”, “methodology”, and “methodological”).
