BTT: Down-sizing

What’s the largest your personal library has ever been? What’s the greatest number of books you’ve ever owned at one time? (Estimates are fine.)
Is your collection NOW the biggest it’s ever been? Or have you down-sized?
What’s the fewest number of books you’ve ever owned (not counting your pre-reading years)?

Once upon a time, I owned more than 4000 books. That included a lot of textbooks too. When we moved to this place, three years ago, I had to down-size. For various reasons. First and foremost was moving to a smaller place and second being, there books I was never going to read. Some had served their purpose too. I  donated around 1500 books to various places..old age homes, children's homes, and local library. I even had my friends pick and choose. 

When I moved to this place, I owned around 2500 books. I still give away a lot of books to the above mentioned places yet I keep adding too, as we all do. I suppose what I own now is the lowest numbers of books, I have ever had. Because I gave away 300 books just few days back and it should stand around 2400! I will stick to that. I have decided not to accumulate. But yes, I love my walls, that is, book walls!
