Features include: * Search supported library catalogs using Title, Author/Creator, and Year filters. * Import records directly into WordPress as Draft Posts using native 2-column Gutenberg block layouts. * Export search results to CSV or BibTeX(. bib) formats for integration with reference managers (Zotero, Mendeley, EndNote).* Clean, single-file lightweight architecture with zero external PHP dependencies. ### External services Supported Catalogs: * BnF – Bibliothèque nationale de France (France) base_url: https://catalogue.bnf.fr/api/SRU Documentation: https://api.bnf.fr/fr/api-sru-catalogue- general Conditions & Lienses: https://www.bnf.fr/fr/conditions-de-reutilisations- des-donnees-de-la-bnf * Hispana – Ministerio de Cultura y Deporte (Spain) base_url: https://hispana.mcu.es/es/sru/sru.do Documentation: https://hispana.mcu.es/en/estaticos/ contenido.do?pagina=estaticos%2Fsru Conditions: https://hispana.mcu.es/es/contenido/ aviso-legal.do Warning: The year field does not work if you select Hispana * DNB– Deutsche Nationalbibliothek (Germany) base_url: https://services.dnb.de/sru/dnb Documentation & licenses: https://www.dnb.de/EN/Professionell/Metadatendienste/metadatendienste_node. html * Library of Congress (USA) base_url: http://lx2.loc.gov:210/lcdb Documentation: https://www.loc.gov/standards/sru/sru-1-1.html Privacy policy: https://www.loc.gov/ legal/security-copyright-and-privacy/privacy-policy/ IMPORTANT NOTICE: Library of Congress Connection Limits (SRU/Z39.50) Please be aware that remote catalog search and consultation via the Library of Congress (USA) SRU/Z39.50 protocol requires network requests through a non-standard port (Port 210). Due to these technical constraints, service availability strictly depends on your hosting environment: * SHARED HOSTING (NOT WORKING): Major hosting providers systematically block outgoing traffic on Port 210 on shared plans for security reasons. These restrictions cannot be modified. As a result, connection attempts to the Library of Congress will fail or time out. * VPS, DEDICATED, OR CLOUD SERVERS (WORKING): The service is fully functional only if your application is hosted on a Virtual Private Server (VPS), dedicated server, or Cloud instance, where the system administrator has full control over the firewall and can open outgoing traffic on Port 210. HOW TO RESOLVE THIS ISSUE: If you are on shared hosting and cannot migrate to a dedicated environment, please contact your hosting provider’s technical support. Request them to explicitly open “outgoing Port 210 to host lx2.loc.gov”. If your provider denies the request, you will need a VPS or dedicated server to use this feature. ## Screenshot [⌊The Serapeum search page⌉⌊The Serapeum search page⌉[ The Serapeum search page [⌊Serapeum\'s search page with export buttons⌉⌊Serapeum\'s search page with export buttons⌉[ Serapeum\’s search page with export buttons [⌊Records found with the import button⌉⌊Records found with the import button⌉[ Records found with the import button ## Installazione 1.

The plugin communicates directly with official library APIs to pull real-time bibliographic data without storing external databases on your server. ### Does this plugin require any external libraries or dependencies? No. It is completely standalone and built as a lightweight, single-file PHP solution utilizing native WordPress functions (wp_remote_get, wp_insert_post, etc.). ### Which libraries are currently supported? The plugin includes built-in endpoint configurations for BnF (France), Hispana ( Spain), DNB (Germany) and Library of Congress (USA). ### What search filters can I use? You can perform targeted queries using Book Title, Author / Creator, and Year of Publication. You can search using any single field or combine multiple fields for precise CQL query results. ### Why do search results vary between different library catalogs? Each institution uses specific indexes and operators (e.g., bib.title, dc.title, or tit). The plugin automatically maps your search fields to the correct CQL schema and operator (= or all) required by the selected library. ### How does the \”Import as WP Draft\” feature work? Next to each record in the search results, click the \”Import as WP Draft\” button. The plugin automatically generates a new WordPress Draft Post pre-filled with the title and structured metadata. ### How is the imported data formatted inside the post? Records are formatted natively using Gutenberg Block Columns (30% width for metadata keys and 70% width for values). This ensures a clean, modern layout that fits seamlessly with your theme without requiring shortcodes or custom stylesheets. ### Can I edit imported bibliographic cards before publishing? Yes. Upon importing, a direct link (\”Edit post #ID\”) will appear at the top of the page. Clicking it opens the standard WordPress Block Editor, allowing you to add featured images, tags, categories, or custom text before publishing. ### Can I export bibliographic results for citation managers? Yes! You can export your search results in BibTeX (.bib) format, which is fully compatible with reference management software like Zotero, Mendeley, and EndNote. ### What data is included in the CSV export? The CSV file includes key metadata fields: ID, Title, Creator/Author, Identifier/ ISBN, Publisher, Date, Type, and Language. ### Does exporting cost extra server memory or database space? No. Export files are generated on-the-fly directly from the active search session memory and downloaded straight through your browser. ### Who can access the bibliographic search tool in WordPress? Access is restricted to users with editors and administrators privileges (manage_options capability) to ensure security and prevent unauthorized draft generation. ### Where can I find the plugin page in WP-Admin? Once activated, a menu item labeled \”Serapeum\” (with a book icon) will appear in your left-hand WordPress admin menu. ### Is there a limit on how many records can be retrieved per search? Yes. To ensure fast response times and prevent HTTP timeouts, the plugin fetches up to 100 records per query and displays them paginated at 20 records per page. ### Can I display search results on the public frontend of my website? This plugin is designed as a backend management tool for editors and administrators. However, once you import records as draft posts and publish them, they become visible to your site visitors as standard WordPress posts. ### Why am I getting an HTTP connection error or timeout? Remote library servers (like DNB) may occasionally experience temporary downtime or rate-limiting. If a query times out, wait a few moments and try refining your search with specific terms. ### I received an error saying \”The response received from the server was empty\” or \”Unable to parse XML\”. This happens if the remote library returns invalid formatting or blocks the request. Ensure your server firewall allows outgoing HTTP requests (wp_remote_get) and that the PHP SimpleXML extension is active. ### Why does a search return no results when I know the book exists? Search terms must match the specific catalog\’s index rules. Try searching with broader terms (e.g., entering only the author\’s surname or a key word from the title). ### Is this plugin compliant with GDPR and privacy regulations? Yes. The plugin is designed with “Privacy by Design” principles. It operates strictly in the WordPress backend and does not collect, track, or store any personal data from your website’s front-end visitors. ### Does the plugin transmit user data to external library servers? All search queries are executed via secure Server-to-Server requests (`wp_remote_get`). The remote library APIs only see the IP address of your website’s hosting server, never the personal IP address of the editor or the end-user. No data is shared with third parties until an editor explicitly clicks “Import as WP Draft” to save the bibliographic metadata locally in your database. ## Recensioni Non ci sono recensioni per questo plugin. ## Contributi e sviluppo “Serapeum Multi-Catalog Bibliographic Search” è un software open source.
