Journals are scholarly communication media among the scientists in the world. Social scientists widely use journals to communicate information on the results of their scholarly research. Over the last few years publication of electronic journals has increased exponentially in addition to print journals. Thus, research on periodicals information services in disseminating information to the users is a timely important effort. This research study evaluates the quality and the extent of information services based on Social Science Journals in university libraries in Sri Lanka under the criteria of effect of service, facilities of periodical sections, collection sufficiency, accessibility, library visits and usage of periodicals. Results show that staff of university libraries in Sri Lanka is prompt and helpful in delivering most of the services to the users whilst some specific services such as document delivery, SDI, abstracting and indexing service are poorly performed or not effectively performed either. I hope, this book will be useful to library professionals, information specialists, students and policymakers or anyone in the field of library and information management.
