I see two issues here:
#1 Re-using recordings in more than one project, which has merit if not carried to the point of absurdity.
#2 Making more of our titles searchable than is currently being done, not a re-using issue, and not requiring additional programming.
Let me focus on #2 for now. We already know we can toggle a project to FIND any title OR author in any LV collection of independent stories, essays, or poems. Why can't we also toggle all the chapters of a book which is equally a collection of independent stories, essays or poems?
Take for instance my recent solo
Voices Of The Night, a collection of poems by Henry Wadsworth Longfellow, many of them famous.
https://librivox.org/voices-of-the-night-and-other-poems-by-henry-wadsworth-longfellow/
It's a collection just the same as any other LV collection, each section being a separate poem with a title. These stand-alone sections could be searchable by title with little to no additional effort, no additional cost, nor tying up additional server space? They are an LV asset individually. Why must be re-recorded and re-submitted into a separate LV collection to be searchable by title. When someone does a google search for
The Luck of Edenhall, for example, the LV audio version should be served up right up along with print versions by poemhunter, poetrynook, etc.
This is another great way to liberate our literature into the PD. If there is good reason why this CAN'T or SHOULDN'T be done, I'd like to hear what it is. "That's how its done and everyone who has been around long enough knows it", I don't consider an intelligible answer.
