Working men of all countries, unite! First published in 1848, The Communist Manifesto is one of the most influential pieces of writing of all time. Written by two leading German philosophers whose names are now universally known, The Communist Manifesto is a documentation of class struggle and the plight of workers under capitalism, and a call for redress. In it, Marx and Engels lay out a searing account of the damage wrought by capitalism, and set out a route towards an alternative: a society without class, private property or a state. Beating a path for revolution and the overthrow of capitalism, The Communist Manifesto is a stirring call to arms that resounds with truth and power today.

This Element describes for the first time the database of peer review reports at PLOS ONE, the largest scientific journal in the world, to which the authors had unique access. Specifically, this Element presents the background contexts and histories of peer review, the data-handling sensitivities of this type of research, the typical properties of reports in the journal to which the authors had access, a taxonomy of the reports, and their sentiment arcs. This unique work thereby yields a compelling and unprecedented set of insights into the evolving state of peer review in the twenty-first century, at a crucial political moment for the transformation of science. It also, though, presents a study in radicalism and the ways in which PLOS's vision for science can be said to have effected change in the ultra-conservative contemporary university. This title is also available as Open Access on Cambridge Core.

One of the most notorious works of modern times, as well as one of the most influential, Capital is an incisive critique of private property and the social relations it generates. Living in exile in England, where this work was largely written, Marx drew on a wide-ranging knowledge of its society to support his analysis and generate fresh insights. Arguing that capitalism would create an ever-increasing division in wealth and welfare, he predicted its abolition and replacement by a system with common ownership of the means of production. Capital rapidly acquired readership among the leaders of social democratic parties, particularly in Russia and Germany, and ultimately throughout the world, to become a work described by Marx's friend and collaborator Friedrich Engels as 'the Bible of the Working Class'.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.
