This site makes it possible to manipulate long inventories of materials to find what you’re looking for.
From the tree on the left of the page, you can choose a group of records. From there, the center of the screen will show a list of everything in this group (or subgroup) of records.
To sort them chronologically, click on the “Date” heading. You can also sort them alphabetically by clicking the “Title” heading, and sort them into their physical arrangement by clicking the “Container” heading.
In some cases, there may be a list within a list — the container information will say “Multiple Containers”. Simply click on that title to see the contents held within.
