To add visual document navigation functionality to a SharePoint document library you will need to create a column of type Ontolica Preview Column for Libraries. Activating the Ontolica Preview for Libraries feature in the site collection features list makes the *Ontolica Preview Column for Libraries *column type available to all document libraries in that site collection. This column is added to a document library like any other column and the Ontolica Preview Web Part will be added automatically.

To proceed go to the document library to which you would like to add the functionality and select the Library link from the top link bar and select the Library Settings in the Settings of the Library ribbon. In the Document Library Settings page click on the Create column link under the Columns heading and that will open the Create Column page. Give a name to the column and select the Ontolica Preview Column for Libraries option in the Name and Type section. If you select the Ontolica Preview column type before giving a name to the column then Ontolica gives the default name for column as Preview. But if you type a name first and then select the column type then the selected name will be preserved. When you select the type for the column you will see a warning/information regarding possible lack of support for this type of column by earlier versions of client programs on the page.

A column with a small magnifier image (default) for each row will be added to the existing list of columns in document library. The color of the magnifier icon for a document will be grey until it gets crawled by the Ontolica Preview Gatherer service and its color gets changed to blue after it is crawled. In the Ontolica Preview configuration pages the magnifier image can be replaced by a small thumbnail image of an actual document. Please note that even if the default magnifier icon has been changed to the small thumbnail image you will still see the magnifier icon before the document in question gets crawled by the Ontolica Preview Gatherer service. Placing the mouse over the magnifier/thumbnail will display the first-page-preview image of a document/page and clicking that image will show full-document-preview images for that document/page. To close the pane with full document preview images you need to click the magnifier/thumbnail preview image again.

Please note that if you are using the Group By feature for your document library view then you will not see the Preview magnifier/thumbnail image, although you will see the title of the column. To be able to see the Preview image the value for the Group By setting should be set to None.
