The bibliography now includes the seminal works of Ferdinand Lassalle, Eduard Bernstein and Carlo Rosselli (namely, The Working Man’s Programme, Evolutionary Socialism and Liberal Socialism), all foundational to the development of democratic socialism and, subsequently, social democracy. Thanks to the indefatigable Internet Archive, the new entries for Lassalle and Bernstein include links to the full texts of the works in question. As for Rosselli’s Liberal Socialism, I’d highly recommend purchasing the Princeton University Press edition, edited and featuring a lengthy introduction by Nadia Urbinanti.
