you can see a tab 'Scan' on the page. If there were Scans availible it would list the hyperlink to them there. In cases when it says there are no Scans, like in this case, you have to contact or go to the archive to receive copies of the book pages. It helps to think of the szukajarchiwach page as a listing of all holdings of the Polish archive, not as a listing of online resources. Only sometimes you can be lucky and there are scans online "in addition to the listing".
