I think you mean the version of your installed *packages*, since R 
libraries do not have version numbers.

For one package, you get an oveviwe using
   help(package="name")
or condensed
   packageDescription("name")
or more condensed
   packageDescription("name")$Version


For a list of all installed packages including version numbers:
  installed.packages()
