Journal
For Journal Title and Abbreviated Title searches, enter the title e.g. new england journal of medicine. These searches are by default executed as an exact search. By entering the journal title (without single quotes) and deselecting the check box for exact search, a phrase search is carried out. Entering e.g. journal of biochemistry the international journal of biochemistry and cell biology is also retrieved.
ISSN and CODEN searches are carried out as a phrase search in the appropriate fields. For ISSNs, you may do this with or without a hyphen, e.g. 0028-4793 or 00284793. For CODEN searches, use the five-character code (without the checkdigit), e.g. NEJMA. Please note that CODEN codes are no longer assigned to new journals.
