Page 115 - 42 Rules for 24-Hour Success on LinkedIn: Practical ideas to help you quickly achieve your desired business success.

The most basic way for people to build their
network is to start with their personal contact lists.
People in these lists might include someone you
have worked with, collaborated on projects with or
maybe attended school with.
To add people to your network, you can invite them
one at a time and enter their email address into the
Quick Invite box or Add Connections button. If you
are a brand new user, this is recommended, so
that you can begin to get an understanding for how
the process works. You will need to know their First
and Last Names as well as their email addresses.

Invite Connections Already On LinkedIn
For a quicker method, you can quickly see which
of your contacts are already on LinkedIn and invite
them en masse. You can upload your contacts
from Outlook or upload a .CSV file of your contacts
into the "Other Contacts" section of your LinkedIn
account.

Using LinkedIn's Colleague and Classmate
Reconnect
Colleague Reconnect enables you to find current
LinkedIn users whom you may have worked with in
the past or may currently be working with.
