22 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 / /ng732 Use DOI for all inbound links to NPG products! Document Delivery Revenue is increasing Added DOI Search to nature.com

23 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)
