5. Article-Level Metrics or altmetrics? What are
we talking about?
Article-Level Metrics (ALM) are a
comprehensive and multi-

7. Altmetrics data is aggregated from many
sources

8. Altmetrics sources can be categorized
Usage
HTML views, PDF/XML downloads (various sources – journal, PubMed
Central, FigShare, Dryad, etc.)
Captures
CiteULike bookmarks, Mendeley readers/groups, Delicio.us
Mentions
Blog posts, news stories, Wikipedia articles, comments, reviews
Social Media
Tweets, Google+, Facebook likes, shares, ratings
Citations
Web of Science, Scopus, CrossRef, Pubmed Central, Microsoft Academic
Search

9. Ideal altmetrics source should provide data
that is
Relevant to the body of knowledge
Available in machine-readable form (API)
Immune to gaming
Free to redistribute (CC-0)

10. Altmetrics business models
usage stats
non-profit publisher provided by
publisher
coverage of
Altmetric for profit all journals
coverage of
service
non-profit books, datasets,
provider
etc.
for profit value-added
services

30. Getting started as a librarian
Collect and track altmetrics
• For research articles published at your university
• For research of interest
• Display altmetrics on author bios
Tell publishers that you want Article-Level Metrics for every
published research article
Tell altmetrics sources that the data should be CC-0
Join the #altmetrics and altmetrics Google Group discussions
30

31. Getting started as a publisher
Collect and display altmetrics for the articles you publish
Work with an altmetrics service provider or install an Open
Source altmetrics application
• Take into account cost, technical expertise, but also
who owns the data
