The Role of the Teacher-Librarian........Swimming???

Yes, I know......I've heard them all before.
Librarians just sit around and read books all day, unless they're dusting the shelves or putting books away or loudly and expertly "shushing"children who dare to enter, Right??
WRONG!!!!
In preparing for my second assignment, I was directed to read three authors' views on the roles of the Teacher-Librarian. Having worked in the 'position' for the past 5 years, I assumed I had a bit of a handle on this.
WRONG AGAIN!!!!
I must be crazy......no-one could possibly in their right mind CHOOSE to do this job. I mean, how can one person in a school possibly fulfil all the duties defined by these authors (Herring, 2007. Purcell, 2010. Lamb & Johnson, 2008), between the hours of 9 and 3 that we all know teachers work, at the level of expertise expected?
There's Teacher, Librarian, Information Services Manager, Information Literacy Leader, Curriculum Leader, Information Specialist, Instructional Partner, Website Developer, Budget Manager, Staff Manager, Fiction and Non-Fiction Advocate, Leader, Program Administrator, and so the list goes on......
When I look at this list, I see that each specified role could be filled by one person, not one person filling every role! It just seems too huge! And that's not even taking into account all the extra little things that we as teachers of young children do on a daily basis like counselling and developing social skills.
I get the Teacher and even the Librarian aspect of the role, but Information Services Manager? Curriculum Leader? Instructional Partner? Website Developer?
All of a sudden, I'm feeling so un-prepared for this. How can I manage information services unless I'm an expert about those services? And how do I become a leader of curriculum, unless I know intimately about the curriculum being taught and am willing to invest time in thinking and talking about the best ways to teach it? How do I become an instructional partner, unless I have teachers willing to partner with me and risk the taunts of others about working with 'the Librarian'? How do I become a website developer when I've only just learned how to blog?
Even with what I've learned so far about time management (see earlier posts), the task seems incredibly daunting.
I guess I'll just do as one of my other lecturers says.......take small steps.....every day.
Do little things well.....celebrate the successes, mine and others'......and in the words of Dory (Finding Nemo)......
Just keep swimming, swimming,swimming......just keep swimming, swimming, swimming.......
