Series, serials, and volumes can be entered in any number of ways, and datasets are rarely consistent. Search results are sorted first by title and then by volume. So, when the series name and/or volume number are entered in different ways on different items, the items may sort incorrectly and be harder to find. We recommend that you choose one uniform way of representing series and serials information and make sure it's applied consistently from item to item within a particular series.
For example, here's a search for "hunger games." See the first one? It's a bit out of order because the title and series are formatted differently.
- Title: The Hunger Games: Mockingjay vs. Mockingjay
- Series: The Hunger Games vs. The Hunger Games trilogy
In this case, it's not that big of a deal, because you can see all of the items on one screen and figure out which one you're looking for. But that won't always be true, especially in a more vague search or for a series or serial with a lot of volumes.
