It's a fruitful partnership. Faculty's expertise of discipline combined with librarian's knowledge and skills in information literacy assist students in improving their capacity in finding quality information resources for the learning and researching purposes.
Yes definitely. Collaboration between Librarians and Faculty with regard to academics and research is worth carrying forward. Librarians at large are knowledge professionals ... and faculty stand out for specific specializations .... the collaborations would go a long way in refining and redefining information search techniques and strategies.
Such collaborations can indeed be highly useful for both sides. In our institution workshops conducted in collaboration on searching skills and efficient use of library resources proved quite useful.
There are questions, where it comes to publishing, that only librarians can answer properly, simply because they have the resources. In bibliometrics studies it is sometimes important to make a distinction between "refereed" and "non-refereed" publications, and in case of doubt (which happens quite regularly), librarians have much better means to find an answer. Also when basic metadata is missing or is ambiguous, librarians know where to look for answers. In general, collaboration between people with different background can only improve the quality of papers. I've seen many badly written papers, probably because the author never had to explain the paper's content to somebody outside his/her field. Of course, there are also people who are just unable to even form basic coherent sentences :-)
