Myth
Librarians are frumpy women of a certain age who ssh a lot and stamp books all day. 
Fact
A qualified Librarian, who has an accredited degree, can work in the following careers: Librarian in a school, university or public library; Records Manager for the health sector or law firms; Information Researcher or Analyst for companies, media outlets, politicians or academics; Archivist and a Systems Manager or Designer. The list is endless and the roles break down into various specialisms such as classification, cataloguing, subject librarian and information retrieval system designers of tools such as gateways, thesauri and bibliographies.
How do I become a Librarian?
To become a Librarian you need to follow a degree course accredited by the Chartered Institute of Library and Information Professionals (CILIP). After the degree you can become an Associate member of CILIP and register for Chartership the moment you find your first professional post. CILIP offers a longer route to Chartership for unqualified Librarians who are working in a professional role, but I would not recommend this as a preferred route for younger people, who really have to hit the ground running in today’s job market. Although it recognises experience in a particular field, it does not offer the range of skills or access to resources available in a higher education institute. Universities have a wealth of current resources including; highly specialized,experienced tutors and vast electronic databases. For example, at The Robert Gordon University in Aberdeen, I was lucky to study under Professor Reid the President of CILIPS (Scotland). CILIP accredited degrees are also recognised by the American, Canadian and Australian Library Associations.
The degree course
You will usually study for a 3 year BSc (Bachelor of Science) or 1 year MSc (Master of Science) in Information and Library Studies. The topics studied will include: Research skills, Human and Financial Resource Management, Technical Skills (Cataloguing/Classification), Information Retrieval, Resource Management and Reference and Enquiry Services.
What personal attributes do I need?
This all depends on what area you wish to specialise in. If you gravitate towards the more traditional roles then a love of books helps, along with a high general knowledge. If you have a flair for IT you may wish to specialise in systems management and design. The most important attribute of all is the willingness to put aside personal preference and help your users to find the information they want as efficiently as possible.
