· Full text of article not returned when requesting text/plain, even if requestor is entitled to the article.
Bug Fix:
· Field-restricted search with phrase containing = is not properly translated. So a search like title(p s = 7 TeV) will have the = incorrectly translated to the operator IS.
We have established a more comprehensive connection between the primary documentation site (http://dev.elsevier.com) and the functional interfaces (http://api.elsevier.com).
Bug Fix:
· HTML response is not returned for all users. Should honor the same entitlement rules as JPEG image.
Bug Fix:

Enhancement:
· Added country as a sortable field.
· Removed certscore as a sortable field.
New API to expose Author Feedback interfaces

Bug Fix:
Address issue where dc:creator entries are not found when full text author does not have authors in ce:author-group/ce:collaborator.
Bug Fix:
DOI searches contain "<" and ">" characters result in zero results due to improper encoding of the search.
Bug Fix:

Enhancement:
· Support for HTML response (anchor snippet).
Enhancement:
· Allows submission of additional metadata fields in usage record (event-time, session-id, and user-agent).
Bug Fix:
· Address issue where empty author profile information returned when submitting a abstract document identifier (Abstract EID).
Bug Fix:
· Fixed issue preventing searches by DOI from being returned.
· Onboarding support within the API authentication framework, including enforcement of APIKey throttling.
Enhancement:
· Support for Open Data attachment retrieval (i.e. open access attachments within documents that aren’t open access).
Bug Fix:
· Fixed issue where ‘subj’ parameter was not being processed.
Performance Enhancement:
· Improvements in implementation of author and affiliation retrieval for COMPLETE view or when any field selections relating to author or affiliation information.
· Introduction of the AUTHORGROUP view, which returns the same fields as the current COMPLETE view. Eventually authors and affiliations will be removed from the COMPLETE view and only returned in AUTHORGROUP. AUTHORGROUP view is limited to 25 documents per request.
Enhancement:
· Allow administrative capability for “Get Annotation Satellite by URI” and “Delete Annotation Satellite by URI” functions.
· Expose “Auto-Complete Concept Label Search” capability.
Big Fix:
· Fixed missing ‘affiliation’ sub-element when requesting field=author.
Bug Fix:
· Book volume title not displayed properly.
New:
· Incorporated to support API authentication framework, including enforcement of APIKey throttling.
Bug Fix:
· Fix to Scopus Search API not properly handling ‘&’ when it appears in field-restricted phrase searches.
Enhancement:
· Performance enhancements for search requests returning author and affiliations. Responses will now include only the data available in the abstract document itself, which may result in slight discrepancies in the affiliation details when part of a parent affiliation.
Enhancement:
· Updated ‘Scopus’ watermark logo for image-based citation counts.
Big Fix:
· Fixed an issue where any scopus_id used resulted in a “not_found” response for metadata (i.e. textual) requests.
Enhancement:
· Support for new CrossRef header ‘CR-Clickthrough-Client-Token’ as a way of passing prospect tokens.
· Support for new Dublin Core and PRISM metadata elements, including:
o dc:format (contains response mime type, ex. ‘text/xml’)
o dcterms:subject (contains author keywords)
o prism:publisher (contains portion of copyright)
o dcterms:isPartOf (contains urn for isbn for nonserial)
o prism:number (contains issue number or range)
o prism:issueName (contains special issue titles)
o prism:pageRange (contains start and, if available, end page range)
Enhancement:
· Beta:
o Can be accessed by sending the query string parameter ‘useRetrieval=true’ OR sending a resource version of ‘new’ (i.e. query string parameter ‘ver=new’ or HTTP header ‘X-ELS-ResourceVersion: new’).
o Optimized response performance for search requests, particularly for those returning element in the COMPLETE view. Responses now include only the data available in the abstract document itself, which may result in a loss of detailed elements, primarily those associated with AUTHORS and AFFILIATIONS.
· Return of ‘article-number’ in ‘coredata’ section of the response.
· New functionality to return citation count as metadata responses. This supports the ability to retrieve the counts for multiple identifiers. Note that the ability to retrieve this metadata is considered a separate resource, which is not enabled by default for all users.
· Revisions to support request payload as defined by the Content-Type application/vnd.crossref.det-envelope+json;v=1.0.0. The payload looks something like this:
{
"uuid": "e583eca0-fdf4-45ff-8c8e-2c3ce1196ea7",
"message-type": "counter-download",
"source-token": "hZqJDbcbKSSRgRG_PJxSBA",
"message":
{ "doi": "10.1016/S0014-5793(01)03313-0", "content-type": "application/pdf", "user-ip": "127.1.1.1" }
}
Where:
uuid: an identifier that uniquely defines the envelope and is meant to enable idempotent processing of reported events. This will functionally replace passing the query string parameter ‘reqId’ or the HTTP header ‘X-ELS-ReqId’.
message-type: a string that identifies the content type of the message
message: a JSON object containing the application-specific message.
Enhancement:
· Supports the ability to specify ‘application/xml’ as a response format.
· Support of comma-delimited list of identifiers in the query string parameters ‘pii’, ‘doi’, or ‘eid’. Note that use of scopus_id and pubmed_id are not supported as multi-identifier requests.
· Return of ‘scopus_id’ or ‘pubmed_id’ in the response payload when either of those identifiers is used in the request.
Enhancement:
· Omit initials from ‘authname’ element if given-name is provided. This eliminates the potential duplication of initials when given-name contains initials.
· Return of ‘pii’ in the response, when available.
Enhancement:
· Return of metric ‘IPP’ in response, which is returned as an element or list of elements similar to SJR and SNIP.
Bug fix:
· Responses with UTF-8 characters are not properly encoded.
Bug fix:
· Fixed an issue where navigation links in the search responses were built incorrectly when the request included a facet ‘count’.
ex.
http://api.elsevier.com/content/search/scidir?start=0&count=25&query=heart&facets= srctitle%28sort=fd,count=100%29&httpAccept=application/xml
· New API to allow non-publishers to log usage records for tracking end-user article access.
Enhancement:
· Provide the ability to retrieve entitlement status for multiple document identifiers by specifying the comma-delimited list in the query string.
Enhancement:
· Provide the ability to search by orcid.

· Requests using identifiers ‘scopus_id’ and ‘pubmed_id’ returned “not found” errors.
Bug fix:
· “Get Similar Describes Resources for Annotations” was not working properly.
· Renamed API from “Abstract Citations” to “Citation Overview”.
· Provided the ability to exclude self-citations for specific authors.
Bug fix:
· Fixed an issue that prevented the ability to filter a request as a union between subscribed sources and open access content. This can be done by submitting the query string parameters ‘subscribed=true’ and ‘oa=true’.
Enhancement:
· Inclusion of article-number in search response.
Bug fix:
· Fixed an issue that involved links to the Scopus web application being improperly constructed inward links.
Enhancement:
Ability to suppress navigation links using the query string parameter 'suppressNavLinks=true'.
Field name 'subject' changed back to 'subject-area'.
Support for the following field selections:
Bug fix:
Return of API-enhanced author elements was missing for simple-articles.
Incomplete data for RDF format.
Enhancement:
Support for the following field selections from the original text of the abstract:
New resource: "Get Similar Describes Resources for Annotations".
