There are three sub-libraries available under the “shared libraries” on the left sidebar:

(i.e include a remarketing list of people who have recently visited the website and exclude a list for visitors who filled an enquiry form)
- Campaign Negative Keywords. Negative keyword lists that you can use accross the multiple campaigns. This may be very useful tool for sharing lists of common negative keywords such as towns, counties, countries, competitor brand names or any other combination of negative keywords. Actually those lists can be very valuable, because you can always download these lists and use them for multiple client adwords accounts.
