Dear Biswas, you and we all know that these things can't be equal each other. Each one has its own value.
UGC some some times given relaxation of NET to Ph.D. & M.Phil holders. Because to give the more and more employment (as i think). I think net sud be necessary for only lectureship not for the Assistant Librarian post. because lecturer has to teach to students, in case of Assistant librarianship experience sud be better not NET. A NET holder can became direct Asstt Lib, on the other hand one candidate having 4 or 5 years exp. in academic library without NET, so he/she can't became Asstt. Librarian. May i ask this question WHY?
other hand, Ph.D in any subject has more value, NET is just a test.
Dear Parvez Ahmad ji
I am full agree with you. For the post of Assistant Librarian net is not necessary. If a person working in college library and Librarian come direct on Assistant Librarian but a future of other staff in the college library. Hierarchy of promotion will stop there and person are working there will be first-rate with the situation. It is necessary that a experience is must for this type of post.
