My poster will focus on a case study. More precisely I propose to create a poster on Delpher, the full-text search engine of the Dutch National Digital Library, which started out two years ago as a joint project of the National Library of The Netherlands and the University Libraries of Amsterdam, Groningen, Leiden and Utrecht. In line with the topics listed for the conference and the objective of sharing best practices I intend to discuss our experiences in setting up the Delpher network and in obtaining the access rights which have been negotiated with publishers and collective rights organizations – two elements which make Delpher unique within the current digitization landscape. Over the last few years, there have been a number of (inter-)national initiatives to integrate digitized collections and make them available to the academic community. Delpher is a pioneer in this area since it is a joint effort of over 50 organizations on a national level and thus gives access through a single platform to millions of pages from newspapers, books, journals and news bulletins from university library’s, musea and heritage institutions. This allows users not only to search in the National Library’s own collection, but to quickly cross-search the collections of all these different organizations from a single online location.

In this poster I will also discuss the innovative system which the National Library of the Netherlands has developed to give users location-based access to its contents, as well as other interesting features of Delpher, such as the search option offering historical spelling variants or the addition of manually-corrected OCR texts.
