The digital project Diário da Grande Guerra: testemunhos portugueses [Diary of the Great War: Portuguese testimonies] has been created in 2014 by the Biblioteca Nacional de Portugal in Lisbon as a part of its Biblioteca Nacional Digital. In this project entries for each day of the First World War show selected items such as photographs, sheet music, newspaper clippings and maps, which thus create a kind of current digital diary. Each day new items are being added in a Today In History rhythm; in 2016 you could not yet access materials for 1917 and 1918. The news shown came also from outside Portugal, and helps documenting the perception in Portugal of the First World War. The project can only be viewed in Portuguese.
The digital collection I Guerra Mundial: Colecção de Cartazes da Biblioteca Nacional has been created by the National Library of Portugal in Lisbon. This collection contains 256 posters from the period 1914-1923, mainly American and French posters. You can browse the gallery with all posters or check the overviews for content and artists. The website contains also a bibliography about First World War posters and Portugal in the First World War, and an overview of some twenty other digitized First World War poster collections worldwide. The website can be viewed only in Portuguese.
The digital portal Portugal 1914-1918 has been created to present the history of Portugal and Portuguese soldiers during the First World War, and to stimulate active interest for the centenary of the First World War. The portal is an initiative of the Instituto de História Contemporânea at the Universidade Nova de Lisboa. On the portal a virtual memorial will be created of Portuguese soldiers serving in Flanders and Africa. The portal promotes the project Memories of World War I 1914-1918 with the aim of presenting materials given by Portuguese people eventually at the European portal Europeana 1914-1918. Portugal remained a neutral country until March 1916. The portal can be viewed in Portuguese and English.
The European Film Gateway 1914 is a part of the European Film Gateway dedicated to films and other audio materials from the First World War held in various European collections in twenty countries. The materials shown are newsreels, documentaries, fiction and propaganda, all in all some 660 hours from 5,600 documents. There is an accompanying project website for background information. The EFG has also created a virtual exhibition on the subject of European Film and the First World War. The user interface is in twelve languages.
Europeana 1914-1918 is a portal project of Europeana, itself a digital portal, too, to bring together resources, both texts and images from all corners of Europe. Special attention is given to materials hitherto hidden away or especially brought to attention for this portal by the general public. Among the documents are letters, diaries, photographs (including stereographs, mostly from the Imperial War Museums), official documents, films, sound recordings and postcards. One of the strong new features is the integration of materials from Australia, New Zealand, Canada and the United States. You can also search for the various fronts. Europeana 1914-1918 had in 2014 an interface in fifteen languages, currently (2018) you can choose from 27 languages.
The films available at the European Film Gateway 1914 can be found here, too. Collections from many European libraries and other cultural heritage institutions are also present at the portal Europeana Collections 1914-1918.
