EB: In this website, and in informal conversation, "EB" is short for "eclipsing binary" -- of any kind! Not to be confused with "EB" in the GCVS or VSX, which means an eclipsing binary with a beta Lyrae light-curve morphology, as opposed to eclipsing binaries with EA or EW light curve morphologies. Both of the general variable star books listed in the bibliography (i.e. Percy, or Hoffmeister et al.) explain the differences between the different types of EBs.
