Sort by popularity

[vanillajonathan]

I think it would be a nice to be able to sort books by popularity.

Maybe even have "Top this week", "Top this month", "Top this year".

This came up on the mailing list in Aug 2023: https://groups.google.com/g/standardebooks/c/aXTXFahZeyM/m/rlVWM9zjBAAJ

It's a good idea, but still a long way away.

Is a real database essential for this? I don't know PHP, but could APCu's apcu_inc be used to count downloads with some periodic synchronization that pushes to a Git repo? It doesn't need to be super accurate or up-to-date; even just committing the download stats once per day would work for the purposes of this issue.

I suppose a real database isn't strictly required, but we should aim to move ebooks into a database in the long run anyway. Keeping things cached in APCu made sense when the corpus was small, but we're approaching 1k works and rebuilding the cache is becoming prohibitively time consuming.

So, if we do something like popularity, we should build it on top of a correct foundation, instead of building popularity first and then having to change it once we migrate to a DB.

Also, keeping popularity in APCu begs the question of what happens when the cache is restarted, for example in a crash, server reboot, or plain old FPM reload. We'd lose all the history immediately!

There's a couple of reasons why I think standardebooks.org should not implement this. Let's first understand what the request is.

Project Gutenberg has its books sorted according to the number of downloads, and there is an alphabetical option too. Can we also introduce the popularity option on Standard Books?? Bc I often find myself lost on what to read next among a selection of mostly unknown books, such as the ones in the fantasy section

I think it would be a nice to be able to sort books by popularity.

As I see it people would like to see what popular ebooks are, where 'popular' means what other people are reading. The problem with free/libre downloadable digital media like ebooks (epub) and podcasts (mp3) for instance, is that the number of downloads doesn't really equals popularity like with streaming media where a "download" is an actual view.

Also I think having 'popularity sorting' in whatever form (weekly, monthly, yearly, all time) tends to degrade the 'discovery/serendipity' of a catalog, although I understand that might be a very personal opinion.

I would recommend to look into another solution to adress this user need. Although maybe not maintained by Standard Ebooks there's a list with a proper popularity social layer at:

If there's any issue with linking (or API use of this list) to an Amazon-owned property, there might be an alternative I might not be aware of.

Goodreads doesn't have an API, so all of those entries were added by hand by a volunteer.I think they also may have even recently prohibited more editions of public domain books being added. The 128 books listed there is a small fraction of our almost 1k catalog.

Ah right, hadn't used it for a while (since 2018) and I see the notice just now:

As of December 8th 2020, Goodreads no longer issues new developer keys for our public developer API and plans to retire the current version of these tools.
