Another feature in Scholar Core is Sherpa/RoMEO integration, which can be used to retrieve the copyright & self-archiving policies of various academic publishers. In order to use this feature you must first configure it

Configure this in the Scholar admin menu at 'admin/islandora/solution_pack_config/scholar' by checking the .  Checking "Enable RoMEO attempts" checkbox and providing a Sherpa/RoMEO API key. It will also only work on objects that have an identifier field with the type "ISSN" in their MODS record. Once properly set up, Islandora Scholar will use an object's ISSN number to query Sherpa/RoMEO's database of publishers and return the host publisher's turns on the functionality.  When that is checked, then when viewing a Citation Content Model object when the object has a MODS identifier of type "issn", the person viewing the object will see a tab labeled "RoMEO" which shows the journal policies pulled from Sherpa RoMEO.

There is also a place in the admin menu at 'admin/islandora/solution_pack_config/scholar' to provide a Sherpa/RoMEO API key. No API key is needed.  Instead, there's a cap of 500 requests per day if you don't have an API key, but no cap if you do.  API registration is free-of-charge as of summer 2016 copyright/self-archiving policy which shows up in the object's display.

Importers

Scholar provides options for importing objects from various sources. The RIS Importer and EndNoteXML Importer submodules allow users to take citation data files exported from other sources (such as RefWorks, EndNote or Zotero) and turn them into Islandora objects using the standard Islandora importer interface (similar to using the zip importer). The DOI Importer and PMID Importer submodules work in much the same way, but instead of using files exported by other citation managers they use Digital Object Identifier (DOI) or PubMed ID (PMID) strings.
