Hello, I'm performing a pro-bono consulting in the Philippines and part of my job is to help enhancing a library, which currently uses Koha. This Library is mixed between physical material (circulation in use) and digital material, which are basically links to Google Drive repository. That being said, I would like to ask for some help about the following requirements: - Has anyone implemented Open URL for use of Open URL Referrer? - Has anyone implemented some kind on Federated Search? - Has anyone implemented ElasticSearch? - Has anyone implemented SMS notification with no cost (Email SMS perhaps)? - Has anyone implemented Facebook messenger to address questions to Librarians? I would really appreciate if anyone could share some details about the implementations. Many thanks in advance, Ayrton -- View this message in context: http://koha.1045719.n5.nabble.com/Koha-Library-Enhancements-tp5894483.html Sent from the Koha-general mailing list archive at Nabble.com.
