Bit of a rarity these days.

CrossRef have released a tool for bloggers to look up DOIs and insert them into blog posts: So far the tool is only available for WordPress blogs. The idea is that bloggers can use DOIs to uniquely identify papers that they are discussing, while at the same time providing readers with an easy way to go to the site hosting the article, and aggregators such as postgenomic.com can cluster posts about the same paper.

Following on from the discussion of BHL and DOIs, I stumbled across some remarkable work by Robert Cameron at SFU. Cameron has developed Universal Serial Item Names (USIN). The approach is spelled out in detail in Towards Universal Serial Item Names (also on Scribd). This lengthy document deals with how to develop user-friendly identifiers for journal articles, books, and other documents.

In a series of emails Chris Freeland, David Shorthouse, and I have been discussing DOIs in the context of the Biodiversity Heritage Library (BHL). I thought it worthwhile to capture some thoughts here. In an email Chris wrote: I think the perception that there are two "camps" is unfortunate.

Nature precedings is pre-publication server launched by Nature a few months ago. To quote from the website: Unable to resist, I've uploaded three manuscripts previously languishing as "Technical Reports" on my old server. The three I uploaded now have bright shiny DOIs, which may take a little while to register with CrossRef.

Following on from my earlier grumble about how the catalogue of Life handles literature, I've spent an afternoon mapping publications in the "itis".publications table in a copy of ITIS to external GUIDs, such as DOIs, Handles, and SICIs in JSTOR. The mapping is not complete by any means, but gives an idea of how many publications have GUIDs.You can view the mapping here.

I think this isn't supposed to happen, but here's a paper with two DOIs. The first DOI is doi:10.1651/0278-0372(1997)17[253:MPAOTC]2.0.CO;2, which links to a record served by BIOONE.

Playing with the recently released "Catalogue of Life" CD, and pondering Charles Hussey's recent post to TAXACOM about the "European Virtual Library of Taxonomic Literature (E-ViTL)" (part of EDIT) has got me thinking more and more about how primitive our handling of taxonomic literature is, and how it cripples the utility of taxonomic databases such as the Catalogue of Life.
