So far i've been creating and organizing calibre for my books, i tried it to be one library for all books, then i broke it to Fiction, OnlineNovel, NonFiction, and ManualBook. Different Library, sometimes different custom column.
#awards (I dont care if it won in what year or anything, so just stay with Pulitzer, Nebula, Hugo, ManBooker, etc)
#types (ANT, SS, SSC, NVLA, NVLT, OMNI, MAGZ, BundleMultiAuthor)
#superseries
#subseries
Title (
#title_alt) alternative title, or different names of the novel in another language.
Authorcolumn (
#pseudonym,
#editor,
#coverartist,
#illustrator,
#translator, )
in the author i keep the real and pseudonym like Robert Galbraith & J.K. Rowling
#genre (FIC.General, SF.LitRPG, F.Urban, HORR.Comedy, THR.Action, ROM.Adult)
Genre is troublesome, i am not librarian so i think to stick to one site or rules.
