Aaron Schmidt’s 10 points about IM in libraries include:
- Instant Messaging is free (minus staff time)
 - Millions of our patrons use IM every day.
 - For some, not being available via IM is like not having a telephone number.
 - There are three major IM networks (AIM, Y!M, MSN)
 - Y!M and MSN will be interoperable at some point.
 - Trillian is a multi-network IM client, meebo is a web-based multi-network client. Use them.
 - Having practice sessions in-house is a good way to get staff excited about IM in libraries.
 - Staff can communicate in-house using IM.
 - Libraries can choose to have one IM point of contact, or they can choose to divide it departmentally.
 - IM is user-centered and builds relationships with library users.
