I added the Gouda Adresboek 1885 as Item and uploaded each page as Media Item. The AltoXML files where also uploaded as Media Items (see How to upload Alto xml files?), where the filename (except extension) corresponds with the scan of the page. I use the IIIF Server, IIIF Search and Universal Viewer modules. I’m still looking for a way to make the transcriptions more visible (not just search), eg. via a HTR panel.
Are Gouda Adresboek 1885 and https://www.goudatijdmachine.nl/data/iiif/2/99958/manifest the results you are looking for?
