So recently the list of free science books was posted on I Fucking Love Science Facebook page (thanks for that guys), which unfortunately caused a huge traffic “spike” and crashed our servers. But no worries — the tech. support guys are sorting this out and the website should be fully working in about 24 hours. Meanwhile, for those, who can access this post, but not the list of free books, try using this cached version. Also, some links were reported to be broken, as one might expect for such a big list of links. These broken links will be sorted out asap.
