The Elsevier empire – which services belong to it?

Dear readers of my blog: Today I do not want to write about scientific publishing or share my thoughts on it with you. Rather, I need your help!

I want to create a list of the services Elsevier created or acquired. So far I know of theses services:

• the publishing house
• databases (eg. Scopus, Science Direct)
• a repository  (Social Sciences Research Network, SSRN),
• a research information system (PURE)
• an altmetrics service (PLUM)
• a social network/ reference manager (Mendeley)
• a reseach analytics tool (SciVal)

I am quite sure not to know all the services provided by Elsevier. Please help me complete this list by adding other services using the comments or send me hints via mail or twitter.
