More than seven thousand titles were published in London in Elizabeth’s reign

From Shakespeare The World as Stage by Bill Bryson.  Chapter 3 page 51.

The other dominant structure in the city was old Saint Paul’s Cathedral, which was even larger than the one we see today, though its profile was oddly stunted. A steeple that had once pierced the sky to a height of five hundred feet had been lost to lightning just before Shakespeare was born and never replaced. The cathedral that Elizabethans knew would vanish in the Great Fire of 1666, a generation or so in the future, making way for the stately white Christopher Wren edifice we see today.

Saint Paul’s stood in an immense open square, covering about twelve acres all together, which served, a bit unexpectedly, as both cemetery and market. It was filled on most days with the stalls of printers and stationers, a sight that must have been hypnotizing for a young man with an instinctive regard for words. Printed books had already existed, as luxuries, for a century, but this was the age in which they first became accessible to anyone with a little spare income. At last average people could acquire learning and sophistication on demand. More than seven thousand titles were published in London in Elizabeth’s reign—a bounty of raw materials waiting to be absorbed, reworked, or otherwise exploited by a generation of playwrights experimenting with entirely new ways of entertaining the public. This was the world into which Shakespeare strode, primed and gifted. He must have thought he’d found very heaven.

Inside, the cathedral was an infinitely noisier and more public place than we find today. Carpenters, bookbinders, scriveners, lawyers, haulers, and others all plied their trades within its echoing vastness, even during services. Drunks and vagrants used it is as a place of repose; some relieved themselves in corners. Little boys played ball games in the aisles until chased away. Other people made small fires to keep warm. John Evelyn could have been writing of Saint Paul’s when he noted, a generation later, “I have been in a spacious church where I could not discern the minister for the smoke; nor hear him for the people’s barking.
