TITLE: Are there some tables or handbooks of homology and homotopy groups of every manifold which has been calculated?
QUESTION [10 upvotes]: Are there some tables or handbooks of homology and homotopy groups of every manifold which has been calculated? Or are there some tables or handbooks which list some common calculated results of  differential geometry, differential topology and algebraic topology?

REPLY [13 votes]: Matthias Kreck and collaborators have set out to create an encyclopaedic catalog of manifolds and their properties a while ago (http://www.map.mpim-bonn.mpg.de/Main_Page), although I don't think it's quite at a stage where one might describe it as useful. Its aim is to collect all known information about "real-world" manifolds, whatever that means. It's a wiki, so if you're interested in helping assemble such a catalog, you might consider contributing.
Personally I think that the world of manifolds is too rich and, well, manifold, to be usefully catalogued in this way, but I'd love to be corrected.
