Pocket Part is described as a paperback supplement inserted through a slit in the back cover. This supplement is usually keyed to the original publication. Where would you typically find it?

• A. A calendar card
• B. An annual supplementary volume
• C. A digital update
• D. A paperback supplement inserted in a book through a slit in its back cover; usually includes textual, case, or statutory references keyed to the original publication

Answer: (D)

Pocket parts are update supplements that stay with the bound legal volume. They appear as a small paperback inserted through a slit in the back cover and are designed to be keyed to the original publication, so the updates correspond to the exact pages or sections you’re using. This makes it easy to keep a case reporter or statutory compilation current between full new editions. The other options don’t fit because a pocket part isn’t a separate calendar card, an annual standalone volume, or a digital update—it’s a physical add-on that lives inside the same book, anchored to its back cover.
