The Accidental Systems Librarian," second edition, is now available!
"The Accidental Systems Librarian takes the approach that anyone
with a solid foundation in the practices and principles of
librarianship and a willingness to confront and learn about changing
technology can serve effectively in a library systems position—with or
without formal technology training."
I was delighted to share my opinion of the book in a blurb for it, and I'm happy to point it out as an invaluable resource for anyone who's either been dropped into this happy field by accident, or is thinking of choosing it down the line. (It's a great review for the kind of things you'd be doing!)
Give it a look!
