Experiences Problems linking from NPG products to
Nature Research titles NPG journal short titles differed from Medline syntax used by
CrossRef Created pre-query filter. Transforms NPG short titles to Medline
syntax for query – problem solved! AOP DOI registration was too slow via CrossRef
Created end-run process to Handle Server Changing NPG DOI syntax from completely dumb
to internally logical 10.1038/80132 10.1038/ng732
Use DOI for all inbound links to NPG products! Document Delivery Revenue is increasing Added DOI Search to nature.com
Plans
Nature Science Update articles to be deposited and have ref queries built
Inbound links to ELS/EAA – testing now
Further automate process with Content Management System (CMS)
