Lease Morgan: systems librarianship is within your grasp

Eric Lease Morgan answers the question “What should I know to be a good systems librarian?” and ends with this caveat

Please do not be overwhelmed. All of these things can be learned and practiced on your desktop or home computer.

All you need is the ability to read books, the desire to learn, and the time to do it.
