My work-in-progress TBR spreadsheet is up to 692 rows. That is lacking 40-50 paperbacks. Argh, no, I have forgotten the complete set of Nevil Shutes I inherited off my father. That's another twenty-odd. That will be overcounting by about 30-40, because of the way I list omnibuses, and another few are going to be short stories or novellas. It'll still be some way north of 700. Yikes.
Then it'll be down to culling the ones I don't really care about reading - mainly all the junk freebies - which could probably halve the size of the list.
And I'll probably have read a couple more by the time I get it up to date. Although I might have acquired more, too.
I think I need to find some other outlet for my collectorish instincts.
