The objective of Mnemosyne, Digital Library for Rare and Forgotten Literary Texts (1868-1936) is to select, categorize, and make visible in digital format literary texts that belong to a forgotten repertoire in order to allow the historiografical review of the period. Mnemosynehas a repertoire of texts and authors who have remained in the shadow of the great literary figures of the first third of the 20th century. This digital library pretends to be a field of international experimentation for the creation of interoperable semantic networks through which a large group of scholars could generate innovative research and theoretical reading models for literary texts. It can be accessed through http://repositorios.fdi.ucm.es/mnemosine/. Mnemosyneaims to be an open-access digital library allowing data modelling for specific collections(intellectual women, Madrid in the Silver Age literature, children literature, kiosk literature, science fiction literature, personal writers collections, etc.) in support of research and teaching on Silver Age Spanish literature. Through Mnemosyneit can be accessed digital edition of texts. The digitization of these works has been carried out by public and private institutions. The first version of the library is stored on the server of the Universidad Complutense de Madrid Library, itself linked to the collections of the digital library HathiTrust. In a search conducted in HathiTrustin 2012, the names, surnames, and pseudonyms of selected authors were used to locate a total of 2,873 digitized texts corresponding to “odd and forgotten” writers. The Biblioteca Digital Hispánica, which serves as the access portal for the digital collections of the Biblioteca Nacional de España, provided 2,448 works by male authors and 1,017 works by female writers. Now have finished a new collection of interactive editions “La Edad de Plata interactive” with the support of Biblioteca Nacional de España. It can be accessed through http://www.bne.es/es/Colecciones/LibrosInteractivos/Subcolecciones/edad-plata-interactivo.html. Behind the scenes of Mnemosyne’s public presence online, the project is developing with the aid of the tool Clavy. Clavyis an RIA (Rich Internet Application) that is able to import, preserve, and edit information from collections of digital objects so as to build bridges between digital repositories and create collections of enriched digital content. Clavyalso provides a basic system of data visualization, edition, and navigation. Clavyfacilitates the import, export, and edition of records in multiple formats such as MARC21, as well as their integration into Mnemosine’s predesigned model with a view to their export into other compatible formats like XLS (Excel Binary File Format) or XML (Extensible Markup Language). Using Clavy, metadata from HathiTrustand Biblioteca Digital Hispánica have already been imported into the Mnemosynedatabase. The data from these sources was described in MARC21, following the rules for library catalogs. An example could be accessed through http://clavy.fdi.ucm.es/Clavy/?CollectionId=13. Mnemosyneis the digital resource made with the support of three research teams (LEETHIhttps://www.ucm.es/leethi, LOEP https://www.ucm.es/loep,ILSAhttp://ilsa.fdi.ucm) affiliated with the Universidad Complutense de Madrid and funded by the public research projects (FFI2012-34666,RedR+Human: TIN2014-52010-R, y CetrO+Spec: TIN2017-88092-R), and by the private financial aid (S2015/HUM-3426).
