There is a small rule I try to follow when buying second-hand books.
It isn’t a strict rule, because strict rules don’t survive long around book markets.
But it works most of the time.
If I hesitate longer than about ten seconds over a two-euro book, I put it back.
Two euros is the danger zone of book collecting. Cheap enough to justify almost anything. Expensive enough that twenty of them quietly become forty euros and a shelf problem.
Markets make this worse.
Boxes appear under tables, on folding chairs, sometimes just on the pavement. You see a spine that looks promising and suddenly you’re kneeling down, tilting books sideways to read titles that were never meant to be stored horizontally.
The two-euro rule helps because hesitation usually means something.
Sometimes it means the book is damaged. Slight warp in the cover, a faint tide mark from an old spill, the early stages of that smell that makes you perform what I described in The Musty Box Test and the 24 Hour Quarantine Rule

Sometimes hesitation means the book just isn’t very interesting.
Collectors rarely admit this part, but many second-hand books are simply… ordinary. Not bad, not rare, not even particularly old. Just the quiet survivors of someone else’s shelf clearance.
The problem is that markets encourage optimism.
You start imagining that every overlooked paperback might contain something special. A forgotten edition. A strange inscription. A pressed flower from 1983.
Occasionally that optimism is rewarded.
Most of the time you’re just buying another book.
The two-euro rule prevents the slow accumulation of books you weren’t really interested in.
Because when you see something genuinely good, you don’t hesitate.
You pick it up immediately. You check the condition, glance at the price, and carry it around the market like a small victory.
The hesitation test is surprisingly accurate.
If you’re still standing there after ten seconds trying to convince yourself the book is “probably worth it,” the answer is usually no.
Of course the rule breaks occasionally.
Every book collector has at least one purchase that ignored every sensible instinct and still turned out to be interesting.
Mine came from a box under a table at El Rastro.
But that story is for another time.
