The Marx Memorial Library and Journal: Theory and Struggle
In 1933 the Marx Memorial Library and Workers' School was established in London. It hosted evening classes in history, science and political economy and has since grown a collection of books, pamphlets, archives and posters. This library plays an important role in making the history of social justice struggles available to us today. It also has a focus on education within labour movements. Luckily, we can access it online.

Their annual journal, Theory and Struggle includes "comment, reviews, analysis, debate and articles about the theory of marxismn and the history of the british working class and labour movement". Find it at this link: http://www.marx-memorial-library.org/theory-struggle
