I understand that lists or specific book requests are forbidden on SE groups, though I don’t really see why, apart from the fact it would take up lots of time and generate multiple duplicates.
I also saw that on meta, there were several questions about how to deal with lists of books, but I don’t think this is a duplicate because I proposing having the list, or lists, in a specific place and not part of the regular Q/A.
Anyways, a compromise may be to offer a recommended book list for writers. The potential writing books could be proposed in a category like plot, style, characterization, publishing, or romance genre, and then selected with a number of up votes.
I am raising this issue because while manuals are far from the only way to learn about writing, they are a great learning tool. Some Writing.SE members that need to learn more about writing could refer to this list for reference.
P.S. I saw a couple of posts about compiling a Writing.SE ebook, what happened to that project?
