First, it is possible to preselect ‘Manuscript’ or ‘Composition’. Second, there is a list of other filter possibilities below: holding institution, category (plainchant, polyphony, carillon, and texts and treatises), format (choirbook, partbook, other codex, bundle, fragment, roll), origin, provenance (later repositories or owners), support (paper or parchment), miniatures, as well as number of voices, composer, and genre.
This list is adaptive: when preselecting ‘Composition’, for example, only the relevant filters ‘voices’, ‘composer’, and ‘genre’ will be visible. When selecting ‘Manuscript’, only the first seven filters appear. Similarly, selecting one or more of the filters will automatically select either ‘Composition’ or ‘Manuscript’.
For example, selecting the ‘Magnificat’ option within ‘genre’ will cause the ‘Composition’ option to be selected as well. Consequently, the results list will only display Magnificat compositions. (Conversely, typing the term “Magnificat” in the search box will result in a list containing these Magnificat compositions but also the manuscripts in which they are found.)
For the filters which contain longer lists of items, such as ‘holding institution’ and ‘composer’, ‘origin’, ‘provenance’, ‘composer’, and ‘genre’, a scroll bar has been provided as well as a search box.
When using one or more of the filters, the chosen filters will be shown above
the results list on the right-hand side of the page. At the same time, the filter list on the left will adapt accordingly by showing only those options that allow to narrow down further the search.
Category
‘Format’ filters operate on two levels: they indicate both the physical form of the object (codex, roll, fragment, or bundle) and, in the case of codices with polyphony, their function as a choirbook or partbook.
Composer
When selecting one or more specific composers from the list, search results may appear with the name of another composer: this is mostly due to a double or conflicting attribution of a given composition. The reason for this is explained in the ‘additional information’ field in the composition description.
Genre
As in the ‘format’ filter, the ‘genre’ filter combines various levels of genres and subgenres: e.g., both ‘mass’ and its subgenre ‘Requiem’, both ‘chanson’ and the typical formes fixes occurring within the genre (ballade, rondeau, virelai), or both ‘motet’ and its subgenres ‘hymn’, ‘Salve regina’, ‘sequence’ or ‘Stabat mater’ (defined on the basis of their text, text genre, and plainchant genre).
