Here we are at the end of the metrics for public library blogs (I’m not going to discuss “visibility” or how long blogs have been around): Illustrations per post.
Overall, the average blog in Public Library Blogs: 252 Examples had 0.72 illustrations per post; the median was 0.50 illustrations per post. The quintiles:
- Q1: Most illustrations per post: 1.0 to 12.8 illustrations per post.
Average (mean): 2.19 illustrations per post.
Median: 1.44 illustrations per post. - Q2: More illustrations per post: 0.67 to 1.0 illustrations per post.
Average: 0.87 illustrations per post.
Median: 0.90 illustrations per post. - Q3: Average number of illustrations per post: 0.25 to 0.67
Average: 0.47 illustrations per post
Median: 0.50 illustrations per post. - Q4: Fewer illustrations per post: Zero to 0.25.
Average: 0.09 illustrations per post.
Median: 0.08 illustrations per post - Q5: Fewest illustrations per post: No illustrations.
And that’s it. You can identify any blog in the book as to its proper quintile. If your library has a blog and isn’t in the book, you can play along.
Which libraries fit where? Well, for that you’ll have to buy the book–and, since I said I wasn’t pushing it by doing these posts, I suppose I should be gratified that there haven’t been any new sales of either library blog book. Or not.
Soon: The quintiles for the academic library blogs. Same metrics, different results.
