What is shown is either a description or a work catalogue. If a description is shown, the focus is on the beginning of it or on the beginning of a single work within it. Matching search words within the text are not highlighted. To see the work catalogue to which the description is assigned to, click on the title.

If images are attached to a document — as is the rule for the work catalogues ‘I(o) priego la divina maiestade’ to ‘Zwickau’ — then the document is displayed in two columns. The left column contains the text of a description, the right thumbnails of the images on a scale of 1 to 10. If you click on a thumbnail, a new window opens with the image displayed in full size. For more details, go to: Display of Images in Full Size.

Documents without images are displayed in a full-width window.

References to other descriptions and work catalogues are hyperlinks leading to work catalogues.

Large work catalogues such as ‘Hieronymus’ and ‘Historia’ often start with one or more indexes, e.g. of short titles, incipits, printer names, bibliographic references. If rows of these indexes end with GW numbers, then the highlighted parts of the rows are hyperlinks. They lead to descriptions or groups of works within the current work catalogue.
