== Freely-available HIV book == 

 In this edit  added a link to a free HIV book.  I can understand concerns about COI  expressed by TechBear in the edit summary, but I've never been involved in any way with this book, which is truly free - one can download the PDF at no cost, with no requirement for registration, and there are no ads.  My understanding is that the German version is very widely used, and I anticipate that the English version could be.  I support inclusion of this WP:EL as a resource, in addition to any appropriate links that could be embedded in the article text.  Because I cannot prove that I'm not involved, I thought discussion here might be appropriate.
