A way forward

Nothing new from Google techs yet, but some judicious excisions and extractions confirm for my purpose the 2.5K ceiling of my Google Books BHCTILibrary account. The next 2.5K (to a total of 5K) will be placed in an "Annex" generously provided by Mrs. Day. More on that tomorrow- I am meanwhile hunting more OCLC# and LCCNs for the first 2.5K.
