Yes, bending down is a bit of a no-no for me, too. But most of the bookcases are now in the dining-room so when I initially loaded them up I was able to put the big books on the table and then transfer them down onto the bottom 2 rows while sitting on a dining chair between the table and the cases. The new ‘surplus’ were transferred upstairs to my bedroom bookcases packed into an empty picnic basket! (As Cicero wrote: A room without books is as a body without a soul.)
