Search DOIs in CA/CAplus on STN

21. May 2012

Now you can search and display Digital Object Identifiers (DOIs) for approximately 12 million records in the CA/CAplus family of databases, including 75 percent of journal articles that have already entered CAplus in 2012. DOIs provide a permanent and unique identifier for retrieving full-text publications.

The availability of DOI information for specific records can be found in the FA field using DOI/FA or FTDOI/FA. Where available, DOI information is now automatically included in ALL/IALL and MAX/IMAX display formats at no additional charge.
