Hi, folks. I've found that link to Microsoft's specs ( http://www.microsoft.com/interop/docs/officebinaryformats.mspx) is broken on https://poi.apache.org/document/docoverview.html. I think, other links to specs may be broken too.
MS Office file format info can be found here: https://msdn.microsoft.com/ru-ru/library/cc307282.aspx, in this zip: http://go.microsoft.com/fwlink/?LinkId=119249 (but this link can also be unstable) Also, google search form has http in its action, so browsers are warning about http resource on https page. -- Best regards, Konstantin Gribov
