Chapter IV
Mending paperbacks: loose pages, cracked spines, and when to stop
More of my evenings go on mending other people's paperbacks than on making anything new. Most of the repairs are small and quiet, and all of them follow a principle I came to slowly: do the least that lets the book be read again, and leave the rest of its history alone.

Deciding what a book needs
A paperback falls apart in predictable ways. The glue along the spine dries out and cracks, usually where the book has been opened flat and bent back on itself, and the pages near the crack come loose. The cover tears along the spine fold. Somebody tapes it, and the tape yellows and slides. By the time a book arrives on my table it often has all three problems and a coffee ring as well.
Before doing anything, I ask the owner what they want the book to do. A novel that will be read once more and then shelved needs different work from a cookbook that lives open on a counter or a guidebook that goes in a coat pocket. It changes the repair completely. The one answer I steer people away from is 'make it like new', because that usually means taking the book apart entirely, which a cheap paperback does not survive well and which erases the wear that made it somebody's book.
I write the plan on a slip of paper and tuck it in the front: what I will do, what I will not do, and anything I noticed that the owner ought to know, such as a section that is starting to loosen but has not yet come away.
Tipping in loose pages
A single loose page, or a couple, is the most common repair. Tipping in means gluing the page back along a narrow strip at its spine edge, attached to the page beside it. I lay a strip of scrap paper over the loose page, leaving two or three millimetres of the inner edge exposed, and brush a thin line of PVA along that strip. Then the scrap comes away and the page goes back in, lined up with its neighbours at the head and the fore-edge.
The important thing is to glue only a narrow strip. A wide strip makes the page stiff at the gutter and pulls it away from its neighbour, and it will tear out again at the edge of the glue. Too much glue squeezes out into the gutter and sticks the next page too. I close the book with a sheet of waxed paper either side of the repaired page to catch any squeeze-out, and leave it under weight overnight.
If a whole section has come away, I tip it in along its fold rather than trying to glue each leaf. A section that has come loose from the spine glue is usually still held together by its fold, and gluing it back as one unit keeps the pages in the right order.
Old tape and cracked spines
Old tape is the repair I dread. Clear tape from decades ago turns yellow and brittle, and the adhesive underneath migrates into the paper and stains it. The tape itself often lifts at the edges while the adhesive stays stubbornly put. I lift what comes away easily with a thin palette knife and leave what does not. Trying to scrape off the stain usually takes the surface of the paper with it, and the stain is part of the book's story by now anyway.
A cracked spine, where the text block has split into two halves, needs more work. I open the book at the crack, clear out loose flakes of old glue with a soft brush, and work a thin layer of PVA into the gap with a strip of card. The two halves are pressed back together and the spine is squared against a board, then held with rubber bands and left overnight. For a book that will be used hard, I add a strip of thin Japanese tissue across the inside of the spine through the gap.
The cover goes back on last, with a strip of toned paper along the spine fold if it is torn there. I tone the paper with watercolour to roughly match the cover. It is never exact, and I have stopped trying to make it disappear; a repair that is visible but tidy is more honest than one that pretends it is not there.
When to stop
The hardest part of mending is knowing when to stop. A book that had belonged to a friend's grandmother came to me last winter with the cover gone, the text block split into three and several pages torn across. I could have rebound it as a hardback. Instead, after talking it through with her, I mended the splits, tipped in the loose pages and made a simple folder of card to keep it in. It still looks like an old book. It is still hers, in a way a new binding would not have allowed.
Some things I do not attempt at all. Water damage with mould goes back unmended, with a suggestion to find a proper conservator, because I will not have spores on a table we eat at. Books that are valuable, or might be, also go back; the rule at this table is that anything someone might want to sell or insure deserves professional care rather than a hobbyist's evening. And I do not reattach a cover with tape, however nicely the owner asks.
Most books, though, need only an evening's quiet work. The last one to leave the table this summer was a paperback novel with a cracked spine and a dozen loose pages, belonging to a neighbour who rereads it every August. It went home on a Sunday morning with a note in the front and a thin, visible strip of new paper along the spine. A week later she told me she had read it on the train without a single page falling out, which is as good as a mend gets.
