Bach Digital (German: Bach digital), developed by the Bach Archive in Leipzig, is an online database which gives access to information on compositions by Johann Sebastian Bach and members of his family. Early manuscripts of such compositions are a major focus of the website, which provides access to high-resolution digitized versions of many of these. Scholarship on manuscripts and versions of compositions is summarized on separate pages, with references to scholarly sources and editions. The database portal has been online since 2010.[7]
History
In 2000, two years after Uwe Wolf had suggested the possibility of supporting the publication of the New Bach Edition (NBE) with digital media, a project named Bach Digital started as an initiative of the Internationale Bachakademie Stuttgart, but without direct involvement of the then editor of the NBE, the Johann Sebastian Bach Institute in Göttingen. After four years the project remained unconvincing: it lagged behind technically and came to nothing, and its www.bachdigital.org web address went up for sale.[8]
The first steps towards a new project, with the same name, were taken that same year. The aim of making images of autographs and original manuscripts available via the internet was continued from the former project, but aiming in the new project at high-resolution scans, for which the Zoomify application was going to be used. The project would cooperate with the Bach Institute in Göttingen. As that institute was going to cease operations (which eventually happened in 2006), however, the idea arose to merge the institute and the project. With the input of the Göttingen institute, the website was now going to not only display high-resolution digital facsimiles but also offer detailed descriptions of manuscripts and compositions which were drawn from Der Göttinger Bach-Katalog / Die Quellen der Bach-Werke (The Göttingen catalogue / The Sources of Bach's works), developed in Göttingen since 2001. Funding for the project by the Deutsche Forschungsgemeinschaft was secured in 2007.[8]
With Uwe Wolf as a leading designer,[9] the development of the website began in 2008,[10] and the database went online in 2010.[7] At the time, around 40% of the 697 manuscripts of Bach's works held in libraries in Berlin, Dresden, Leipzig and Krakau (which account for about 90% of his works) were made available in digital form.[11] The site not only provides accessibility to the distributed documents but also helps their preservation.[11] Several international libraries made their documents available, including libraries in Europe and the U.S.[7] Works from the period of c. 1700 to 1850, in manuscripts, copies and early prints, have been collected and presented in high-resolution digitized form. New research has been added continuously, for example on watermarks and copyists.[11]
The website hosts separate pages for compositions: the static URLs for these pages start with http://www.bachdigital.de/receive/BachDigitalWork_work_ and end with an eight-digit number (the first four being leading zeros for works in the 1998 version of the BWV catalogue). Each of these numbers thus identifies a work, e.g.:[14]
Apart from later additions and corrections, these numbers follow the collation of BWV numbers, but with alternative versions of the same composition inserted immediately after the BWV number of the composition to which they belong, e.g.:[14]
Primary sources described on separate webpages (many with a facsimile of the original source) similarly have a unique number, which preceded by http://www.bachdigital.de/receive/BachDigitalSource_source_ gives the static URL for that page, e.g.[14]
Writing when the Bach Digital website was in its last stages of development, shortly before going online, Johannes Kepper of Paderborn University thought it would not only satisfy lay visitors feeling adoration for Bach but also had a role for scholars, for instance those initiating new critical editions of his music. According to Kepper, however, Bach Digital is not to be seen as a published edition of the composer's work but rather a collection of annotated sources: in itself it is not a critical edition of Bach's music. He sees another possible use of the website: it allows interested readers to check the quality of published editions of Bach's music and assess editorial choices by comparing such editions with the original manuscripts, displayed in high resolution on the website.[8]
According to Yo Tomita [fr], writing in 2016, databases such as Bach Digital have largely replaced printed scholarship, such as the Critical Commentary volumes of the NBE, as the first point of entry for Bach scholars.[16]
An analysis of database usage in 2016 observed a total of 101,598 views, mainly from European countries, the U.S. and Japan but also from countries such as China, Brazil, Mexico, Vietnam and the Arabian Emirates.[10] In the month of December, 32,537 views were counted, 896 of them for the autograph of Bach's Christmas Oratorio, the manuscript creating the most interest.[10]
