The Biodiversity Heritage Library is hosting a 48-hour data correction event on December 7-9 2015. We’re enlisting the help of you, the BHL community, to help us complete 10,000 pages from BHL’s OCR output that we can then use as a training set to apply to the remaining BHL corpus.

UPDATE: A new and enhanced commenting system is being planned for BHL. The commenting system described below has been disabled as of July 5, 2016. | We are pleased to announce that we have added the ability to add comments to books in the BHL website! This new feature will allow you to easily share your discoveries while reading BHL books, highlight interesting content, post your expertise for others to see, engage in conversations about BHL books from directly within BHL, and easily discover all of the great posts from your fellow biodiversity-enthusiasts.

From the TDWG and BHL Africa Workshop, BHL Director Martin Kalfatovic traveled to Madagascar for the Global Biodiversity Information Facility (GBIF) 22nd Meeting. He met up with Constance Rinaldo (BHL Vice Chair and librarian at the Museum of Comparative Zoology at Harvard).

Problems with the custom PDFs created on the BHL website on 11/22 and 11/23 have now been resolved. The links to access any PDFs that were generated during this time should now work. If you still experience problems, please send us feedback: http://biodiversitylibrary.org/contact. Thanks for your patience!

Have you ever stumbled across a caterpillar and wondered what kind of adult moth or butterfly it would metamorphose into? Short of catching the caterpillar and actually observing what adult it becomes, this answer might be harder to come by than you might think. Most taxonomy and identification has been performed on the adults of various Lepidopteran species, and there are still many species whose caterpillar forms are not readily known. This is particularly true for many Australian species whose early life stages remain a scientific mystery.
