Fetches the abstract text and core metadata for one or more records from the Elsevier 'Scopus' Abstract Retrieval API. This complements the Search API used elsewhere in the package: a search returns many records with a few fields each, whereas this returns the fuller record, including the abstract, for a known identifier.
Usage
scopus_abstract(
ids,
by = c("doi", "scopus_id"),
api_key = NULL,
inst_token = NULL,
verbose = FALSE
)Arguments
- ids
Character vector of identifiers to look up, either Digital Object Identifiers or 'Scopus' record identifiers (with or without the
"SCOPUS_ID:"prefix), according toby.- by
Either
"doi"or"scopus_id", the kind of identifier inids.- api_key, inst_token
Optional credentials (see
scopus_has_key()).- verbose
Logical. When
TRUE, progress is reported.
Value
A tibble of class scopus_abstracts, one row per identifier, with
columns id (the input identifier), scopus_id, doi, title, abstract,
publication, year and citations. A field the API does not return is
NA. An identifier that cannot be retrieved (for example one not in
'Scopus') yields a row of NAs with a warning, so a batch is not lost to a
single failure.
API access
This performs one request per identifier and requires a valid API key and
internet access; full-text abstract access can also depend on your
entitlement. See the API access section of scopus_count() for the
conditions that may be raised.
