LibriVox monthly statistics

[Lucy_k_p]

I'd still be interested to know the total length of the catalogue. How long would it take to listen to everything we have produced? And how much more would we have produced in the time you were listening?

[ScottLawton]

Per request on total duration...

I haven't had time to refresh my data, so can't provide useful info for November. But, here's the background info. (And a caveat: I did NOT check any of this by hand, so could well have made a mistake. If the data seems implausible, maybe it's wrong!)

Scott,

Thank you for the information, I was also curious about this. That is a lot of recorded audiobooks. Here are a few other ways to try to visualize that large number.

5 years, 329 days, 23hrs, 8 min

3,103,148 total minutes

38,790 = 80-minute CDs full of data
387.9 meters or 420.2 yards = shelf space covered by using regular jewel cases for CDs
193.9 meters or 215.5 yards = shelf space covered by using slim jewel cases for CDs

Thanks, Scott, for that. Our figures are certainly down, and I suspect a number of reasons. When I last did any work on this (a couple of years ago), I found that 100 readers had read 50% of all sections. It doesn't take many of that 100 to stop recording or slow down (for one reason or another) to make a huge difference to our output.

Hello

Here's my data.

2005 2 days 00 hrs 13 min 02 sec
2006 25 days 22 hrs 49 min 48 sec
2007 150 days 20 hrs 01 min 31 sec
2008 214 days 08 hrs 36 min 59 sec
2009 275 days 00 hrs 41 min 14 sec
2010 282 days 10 hrs 10 min 23 sec
2011 287 days 15 hrs 01 min 05 sec
2012 276 days 01 hrs 14 min 51 sec
2013 285 days 11 hrs 39 min 45 sec
2014 227 days 12 hrs 58 min 40 sec

I get the recording time through API.
If the time format is wrong, I treat is as 0 sec.
There're logs of wrong format in 2005 & 2006. So this caused the difference from the one by Scott san.

You can see the result at
http://ekzemplaro.org/librivox/statistics/

The code & data is here,

If you use Linux, you can easily run it on your machine.

Cheers,

There're logs of wrong format in 2005 & 2006. So this caused the difference from the one by Scott san.

Masa-san: I posted a new thread in the 'error reports' section and have a question for you over there.

All: the actual 2005 total is somewhat between my result and Masa-san's. I think I incorrectly treated '38:56' as 38 hours rather than 38 minutes. The same error is likely to affect some of my other totals.

Scott

[Lucy_k_p]

And in more completely meaningless statistical analysis (Since our projects vary in length from half an hour for the weekly poetry, to around 40 hours for Russian epic novels) the average length of an individual project is about 6 hours and 20 minutes.

Edit: Thanks for the info Scott and Masa.

[Piotrek81]

Any statistics for the December and for 2014 in general?

[RuthieG]

We catalogued 96 projects in December.
We catalogued a total of 966 projects in 2014.

Total number of projects: 8923
Number of completed projects: 8292
Number of completed non-English projects: 1168
Total number of languages: 91
Number of languages with a completed work: 35
Number of completed solo projects: 4658
Number of readers: 6666

So a considerable decrease in the number of projects catalogued in the year, though numbers seem to have picked up over the last couple of months.

[Carolin]

to beat last years record, we would have needed 9,8 additional books per month, so thats quite a decrease compared to last year. but i have a feeling 2015 will be better

2014 966
2013 1083
2012 1070
2011 1082
2010 1076
2009 1018
2008 883
2007 726
2006 357
2005 31

[MaryAnnSpiegel]

I'm guessing that our catalog goes by California time, since we are hosted at IA, but we're within a couple of hours, so here are some [tentative] numbers for January:

We cataloged 103 projects in January!

the stats:

Total number of projects: 9025
Number of completed projects: 8395
Number of completed non-English projects! 1186
Total number of languages: 91
Number of languages with a completed work: 35
Number of completed solo projects: 4698
Number of readers: 6708
...who have completed something
