bibdoiadd - Man Page

add DOI numbers to papers in a given bib file


bibdoiadd [-c config_file] [-C 1|0] [-e 1|0] [-f] [-o output] bib_file


-c config_file

Configuration file.  If this file is absent, some defaults are used. See below for its format.

-C 1|0

Whether to canonize names in the output (1) or not (0).  By default, 1.


If 1 (default), add empty doi if a doi cannot be found.  This prevents repeated searches for the same entries if you add new entries to the file.  Calling -e 0 suppresses this behavior.


Force checking doi number even if one is present

-o output

Output file.  If this option is not used, the name for the  output file is formed by adding _doi to the input file


The script reads a BibTeX file.  It checks whether the entries have DOIs.  If not, it tries to contact http://www.crossref.org to get the corresponding DOI.  The result is a BibTeX file with the fields doi=... added.

The name of the output file is either set by the -o option or  is derived by adding the suffix _doi to the output file.

There are two options for making queries with Crossref: free account and paid membership.  In the first case you still must register with Crossref and are limited to a small number of queries, see the agreement at http://www.crossref.org/01company/free_services_agreement.html.  In the second case you have a username and password, and can use them for automatic queries.  I am not sure whether the use of this script is allowed for the free account holders.  Anyway if you try to add DOI to a large number of entries, you should register as a paid member.

Configuration File

The configuration file is mostly self-explanatory: it has comments (starting with #) and assginments in the form

   $field = value ;

The important parameters are $mode ('free' or 'paid'), $email (for free users) and $username & $password for paid members.
