> Choosing what to put on limited shelf space is inherently a process of choosing what to remove and to exclude. It is zero sum.

Titles are removed when the card catalogue shows they aren't being checked out. Those titles can be bought by the public at a steep discount.

What is included are titles that are likely to be checked out, plus what individual patrons ask for.

I've done the latter. For some unusual titles I had to supply the ISBN. If they were in print, they were on the shelf within a month.

Excluding books is a recent phenomenon driven by book-banning agendas.

> Books on the shelf is partial transparency. What was excluded, what was removed. What was requested for by patrons but not chosen.

This seems to flow from wholly imagined concerns - ones that are trivially debunked.

What is removed can be seen for sale and is also recorded in the card catalog. What is excluded (when book-banning efforts are successful) is also recorded.

What is requested by patrons is stocked. Again, I've done it.
