I've suggested this in another form, but I am bringing it up again as PBB may be a good way to accomplish this.
It is incredibly annoying to try to find books that included within whole sets of works. For example, try finding City of God by Augustine in your collection. If you own Schaff's Nice & Post Nicene Fathers you have it but it'll take some effort to find it.
I would like to create a book: City of God by Augustine that is just a dummy placeholder pointing to logosres:npnf02;ref=Augustine.De_civ._Dei_1;off=-16
I may actually end up doing this eventually and just make a whole bunch of personal books that contain nothing but a link like that. But I don't think that it should be necessary.
Logos, can you please make a personal book option that would mirror a selection of content that already exists in our library such as this.
Or alternatively, implement one of these uservoice suggestions
