Vector of UTs (i.e., publications) whose cited references you want.
sid
Session identifier (SID). The default setting is to get a fresh
SID each time you query WoS via a call to auth. However,
you should try to reuse SIDs across queries so that you don't run into the
throttling limits placed on new sessions.
The publication that is doing the citing. These are the UTs that
you submitted to pull_cited_refs. If one of your publications
doesn't have any cited refs, it will not appear in this column.
doc_id
The cited ref's document identifier (similar to a UT).
title
Roughly equivalent to the cited ref's title.
journal
Roughly equivalent to the cited ref's journal.
author
The cited ref's first author.
tot_cites
The total number of citations the cited ref has received.
