How does BHL select content to include in its collection?

BHL welcomes content into its collection that are relevant to the wide range of fields that support biodiversity research. We prioritize the selection of content from our BHL Partner collections as well as biodiversity relevant materials available within the Internet Archive “texts” corpus. For more details about our selection process, please review our collection development policy.

As a free, mobile archive for natural history literature, BHL is ideal for 21st century research, which can happen on the field, in a museum, or at a coffee shop, as long as there’s internet connectivity.
