To keep track of the resources in your personal collection, you can add tags that make sense to you, and then filter by them.
Step 1 - Click on the individual record title, and then click on the Add tags to collection link below the title;
Step 2 - A new tag is started every time you enter a comma or space, so if your tag consists of 2 words, make sure you include an underscore to connect them. If you have already added tags to items in your collection, the list of previously added tags appears in a drop-down when you click in the tags field;
Step 3 - When you have finished assigning tags to the resource, click on SAVE. You can then filter by those tags using the funnel icon at the top of the list of resources;
N.B. You can also use the filter function to find readings by Type.
