BHL developers have incorporated the Internet Archive’s open source book viewing application into the BHL portal, providing a new interface for using BHL’s digital books.
We’ve been investigating options for storage and distribution of citation data in the Biodiversity Heritage Library. In particular, we are searching for an appropriate “core” format. The thought is that with an appropriately verbose, open, standard core format for our citations, we can transform that format into whatever other format we might want to support. By “verbose”, we mean a format that can support all of the information that we need to preserve. By “open”, we’re looking for a format that’s not tied exclusively to one system or vendor. And by “standard”, we’re hoping to identify a format that is widely recognized by the library community.
In previous posts we have discussed the issues surrounding the identification of articles contained within BHL scanned books and the new interface we’ve developed that let’s users build their own PDFs for download. In that interface(demo for The Journal of agricultural science, v.7) we ask users who are building a PDF of an article to contribute the article title, author(s), and subjects/tags and we’ll store that information alongside the generated PDF and make it available for other users to search and download.
I wanted to let everyone know about a change that has been made to the search function of the BHL portal.Until now, letters that include diacritics (for example, ó, ö, è, é, û) were treated differently than letters without diacritics.What this meant is that in order to find titles, authors, or subjects that included diacritics, you had to search for an exact match on the diacritic… for example, to find all titles about “invertebrate zoology”, you had to search twice: once for “invertebrate zoology” and once for “invertebrate zoölogy”. (Or you had to search for something like “invertebrate zo” and hope you didn’t get too much extra stuff in the search results.) Obviously, there are all sorts of problems with this limitation.
Following user requests, the BHL exports now include Library of Congress Subject Headings (LCSH) and metadata for all pages in the BHL collection.
Last fall developers Ryan Chute and Herbert Van de Sompel from Los Alamos National Laboratory’s Research Library released djatoka, a new Open Source JPEG 2000 image server.
Since the public launch of BHL in Feb 2008, the BHL Technical development team has received repeated requests for an interface that would allow users to download a PDF for an individual article within one of the digitized books in BHL. This is actually a fairly challenging task, as previously reported, but with the right technology and a little bit of luck we’ve devised a solution that is working very well in production and is receiving positive feedback. Here’s how it works.
BHL’s existence depends on the financial support of its patrons. Help us keep this free resource alive!
The Biodiversity Heritage Library (BHL) is the world’s largest open access digital library for biodiversity literature and archives. Headquartered at the Smithsonian Libraries and Archives in Washington, D.C., BHL operates as a worldwide consortium of natural history, botanical, research, and national libraries working together to digitize the natural history literature held in their collections and make it freely available for open access as part of a global “biodiversity community.”
