Multnomah County Library (MCL) provides some excellent databases that are not available at the PSU Library.

However, you will be asked for a local address (e.g., department building address if you don't live here -- inform your department office manager) for them to send you a welcome postcard (no personal info except for your name).
With the MCL card, you can access most of their databases remotely (from home or elsewhere). Below is a select list of relevant business databases. For a comprehensive list of available MCL online resources, go to Research Tools and Resources.
