Experiences

Problems linking from NPG products to
Nature Research titles



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


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!
10.1038/80132  10.1038/ng732
Use DOI for all inbound links to NPG products!
Document Delivery Revenue is increasing
