Scientific publishing is undergoing significant changes due to immense growth of online publications and increases in the number of open access journals. Most leading publishers like Elsevier, Taylor and Francis, Springer and others have introduced open access journals in a big way and their acceptance among authors for publishing articles has also increased.

As the numbers of open access journals are growing in a big way, it's a challenge for the authors to identify the best journals for their research and publications. So, the present study entitled "Authorship Distribution and Collaboration in LIS Open Access Journals: A Scopus based analysis during 2001 to 2015" is an attempt to analyzed the authorship pattern, collaboration index, degree of collaboration, collaboration coefficient, author productivity, and ranking of prolific authors of LIS open access journals covered in the study during the period 2001 to 2015. The study will be a useful for the authors and researchers in the field of Library and Information Science to be aware about the ongoing trend of authorship, research collaboration, author's productivity of LIS open access journals.
