Locate Updates to Provider Title Lists

Once you've located a set of title lists, it's valuable to figure out how the provider will update these lists and how often.

Step 1: Determine update frequency

Determine how frequently the provider makes updates to their title lists available.
Sometimes the provider will make this information available on the site where they post their lists.
It's possible you may need to determine update frequency by monitoring a provider's lists over time.
If you are in touch with a provider contact, you can ask them.

Step 2: Determine how the provider makes updates available

Determine whether the provider updates by posting new complete lists, posting updates only, or both.
As above, you may need to figure out this information by trial and error or by asking.

Step 3: Determine if the vendor provides an update feed

Some providers post updates as they occur using a web site, RSS feed, e-mail list or other method. (Example)
Search the provider's site to see if you can locate an update feed.
If you are responsible for a provider or subset of a provider's packages, you may want to sign up for these updates.
