The 2015 edition of the Social Science Citation Index in Journal Citation Reports identifies 41 social work journals. Although opinions vary substantially among social work professionals, these are the social journals with the strongest claim to being the best in the field.
My personal favorites on this list include Research on Social Work Practice, Social Service Review, Social Work Research, and the Journal of Social Work Education, but this list clearly indicates my preference for research and teaching rather than clinical work.
I enjoy: Journal of Social Work Practice, Journal of Social Work, Qualitative Social Work and the British Journal of Social Work. Broaden you thinking and take a look at Asia and Pacific social work journals including Aotearoa Social Work. Enjoy your reading.
