It looks like you actually rewrote it by hand?

There's a "plain text" button at the top right corner from which you can simply copy paste:

I have been informed, that when circulating libraries were first opened, the booksellers were much alarmed, and their rapid increase added to their fears, and led them to think that the sale of books would be much diminished by such libraries. But experience has proved that the sale of 'books, so far from being diminished by them, has been greatly promoted, as from those repositories, many thousand families have been cheaply supplied with books, by which the taste for reading has become much more general, and thousands of books are purchased every year, by such as have first borrowed them at those libraries, and after reading, approving of them, become purchasers.
