+# Finding links to the current item
+
+Sometimes it can be hard to keep track from where a certain page is referenced.
+This is especially true whenever you want to reconstruct your website with a greater number of objects being moved or deleted.
+For this situation, you can visit the {guilabel}`Links to item` page, which is an overview of all objects that refererence a certain object.
+
+```{note}
+An item references another item by creating a hyperlink to this item, using the item in a block, or using it in the {guilabel}`Related Items` field.
+```
+
+# Links to item view
+
+In the toolbar on the left side you can click on the item with the three horizontally-aligned dots (called {guilabel}`More Menu`).
+Click then on the item labeled {guilabel}`Links to item`.
+
+You can see now a table displaying all links to the current item.
+
+```{image} ../_static/user-manual/manage/link-to-items.png
+:alt: A panel captioned with "Links to My Summer Vacation - Day 2". A table with two columns (first column labeled with "linked by this item", second column labeled with "review state"). In the row appears a link titled "Links to My Summer Vacation - Day 1", because it is referencing the current item.
+```
+
+For editors this view gives insight, if those links are still relevant or not.
+On second sight, it also helps to prevent potential broken links.
+
+For example, when you try to delete this page with other pages linking to it, you will get a warning that this will cause broken links that lead to a "not found" error page.
+If you receive such a warning, you can inspect this view and go through each referencing page, removing any references.
