A thank-you for your church chained library volunteers: a photo of an old leather-bound book still on its iron chain, or a volunteer's cotton gloves and condition notes beside a worn wooden shelf as a jigsaw

Written by the team behind Puzzlify. Puzzlify is our product, so weigh what follows with that in mind. We've tried to make this useful even if you never use it. We're not affiliated with any parish council, parochial church council, diocese, cathedral, church, churches trust, library, archive, record office, book conservation studio, bibliographical or local history society, heritage trust, heritage body, heritage funder, sponsor, school or community organisation.

It's a cold Saturday morning in February, and the little room above the church porch smells of old leather and dust. Two volunteers are working at a narrow table under the window. One is a retired schoolteacher called Margaret, who is turning the pages of a heavy book with a thin paper slip rather than her fingers. The other is a student called Tom, who is typing her words into a laptop balanced on a cardboard box. "Spine split at the head. Two leaves loose. Old repair with brown tape on the back board, not ours." She pauses, peering at a faded name written inside the cover. "And somebody's signed it. 1694, I think. Or 1664." Tom stops typing. "Which?" Margaret holds the book up to the light, frowns, and lowers it gently back onto its foam support. "Put 'late seventeenth century'," she says. "He'd forgive us."

If you want to say thank you to people like Margaret and Tom, this is a guide to doing it well, with or without a puzzle.

Who we mean

A chained library is a collection of books that were fixed to shelves or desks with chains, so they could be read in place but not carried off. A small number of churches, cathedrals, schools and old institutions still have one, sometimes a whole room, sometimes just a handful of books on a single chained shelf or a lone volume in a case. Caring for them, recording them and helping people see them is often the work of a small, patient team:

• the volunteers who catalogue each book, noting its title, printer, date, binding, chain fitting and condition
• people who check the room's temperature and humidity, watch for damp, mould and insect damage, and report it to the church
• volunteers who dust shelves and boxes carefully, following advice from conservators
• researchers who study former owners' names, inscriptions, marginal notes and the history of the collection
• the guides and stewards who open the room on heritage days and explain why the books were chained
• people who write the guide leaflet, a display panel, a church website page or a talk for the local history society
• the churchwardens, the parochial church council and any trustees or advisers who decide how the books are looked after

Why a thank-you matters here

Old books in a church are fragile, easy to forget and expensive to put right once damage has set in. The people who look after them often work in small, cold rooms, a few hours a month, for years, and much of what they do is simply noticing: a new damp patch on the wall, a beetle hole that wasn't there last spring, a chain rubbing against a binding. Most visitors only see the room for ten minutes on an open day, if at all. A thank-you that names something specific, the inscription they found, the talk that made you look twice, the box they made for a crumbling volume, can mean a great deal.

A little honest background

It helps to get the basics right in a note, because people who care for old books usually know a great deal and are rightly careful about detail.

Not every old book in a church was chained, and not every chained library is in a church. Some collections have been moved, sold, split up, lent to a record office, cathedral or university library, or rearranged over the centuries, and chains and fittings are sometimes later replacements. Dates, owners and origins can be uncertain, as Margaret's "late seventeenth century" shows. If you're not sure of a detail, "thank you for looking after the books" is safe and true.

Old books and their chains should be handled only by people the church has trained or authorised, and usually only with clean, dry hands or the method a conservator recommends. Never pull a chained book off a shelf, open one fully flat, turn pages by the corner, rest anything on top of it, or try to clean or repair one yourself, even with good intentions. Many church buildings are listed, and the collection may also be subject to its own rules or the advice of a diocese or a specialist adviser.

If you'd like to support the collection with money, ask the church how it's best given, for example through a fund for conservation, boxes or environmental monitoring, rather than handing cash to a volunteer.

Also worth knowing: photographs of the books, the catalogue and the guide may be protected by copyright or covered by the church's own permission rules. Ask before taking photos and before sharing anything online.

What makes a good photo

• a single leather-bound book on its shelf with the chain running down to the rail, lit from the side
• the volunteer's cotton gloves or page slip, pencil and condition notes on the table beside a closed book, if that's how they work
• a row of spines on a chained shelf, showing the old shelf marks and worn leather
• the iron hasp or rod where the chains are fastened, with the book left exactly where it is
• the small room above the porch or vestry seen from the doorway, with the window light falling across the shelves
• an old photo of the library or a page from an old guide, placed next to a photo of the same shelf today

Getting the JPG right

Use a JPG, sharp and well lit. These rooms are often dim, so use window light or ask whether the room lights can be on, and avoid flash: strong light can be harmful to some old materials, and it glares on leather, gilt and glass cases anyway. Hold the phone steady, or rest it on something stable that isn't a book, and tap to focus on the spine, the chain or the gloves. Don't move books, open them or lay them out for the photo; photograph them as they are, or ask a trained volunteer whether a particular shot is possible. Ask before photographing anyone, and keep children, volunteers who haven't agreed, recent memorial names, alarm panels, key safes, rotas with phone numbers and anyone's personal details out of the frame.

Privacy and an optional PIN

Puzzlify puzzles are private links. You can add an optional PIN so only the person you send it to can open it. Photos aren't used to train AI and aren't shared with third parties.

Say it's from you

Put your name, or your family's, group's or class's, in the note at the end so they know who sent it. A puzzle that ends with "from the man who asked why the books were chained, and now can't stop telling people" is a thank-you, not a mystery.

Piece counts

Rows of brown spines look wonderful but can make tricky puzzles, because many pieces are nearly the same colour; a 252-piece shelf on a phone screen can be hard work, so choose 24 or 48 for children or for a quick smile, and save the bigger counts for a tablet or a computer.

How to send it

Make the puzzle, write the note, publish the link, and send it by email or message, or print the link as a QR code inside a card. The recipient doesn't need an account or an app; it plays in the browser on a phone, tablet or computer. The note appears when the last piece clicks into place. If the volunteer you're thanking prefers paper, a handwritten card left with the churchwarden may be the better choice.

Note examples

• "Thank you for showing us the chained books on the open day. Our daughter now wants to be a librarian."
• "To Margaret: late seventeenth century. He'd forgive you, and so do we. Thank you for every careful page."
• "Thank you, Tom, for typing up the whole catalogue. Somebody in a hundred years will be grateful too."
• "From the local history society: thank you for the talk. Nobody left early, which is a first."
• "From Year 5: thank you for explaining why the books were chained. We still think it's a bit funny."
• "Thank you for noticing the damp before it reached the shelf. The books are lucky to have you."

What it costs, plainly

The preview is free, so you can see how it looks before deciding anything. Publishing the link costs one credit (€3.99), or less per puzzle with a bundle. It's a digital puzzle, not a printed or cardboard one, so nothing arrives in the post. If a card and a few sentences feel like enough, they are.

Ideas that are not a puzzle

• a note in the visitors' book saying what you learned from the volunteers and which book stayed with you
• a short letter to the parish magazine or newsletter naming the library volunteers, so the thanks reaches them
• a donation to the church's conservation fund in their honour, with a note saying why
• coming to their talk or open day, and bringing someone who's never seen a chained book
• offering your own time: stewarding on a heritage day, typing up notes, or helping with fundraising
• a framed print of a favourite shelf, from a photo taken with the church's permission

Where Puzzlify fits

Puzzlify turns a personal photo into a private digital jigsaw that you send as a link. It isn't a printed puzzle, and it isn't a public puzzle board: only the people you send it to can open it. It's one option among many, and it works best when the photo means something to the person receiving it.

If a photo puzzle feels right as well, choose a single chained book, the gloves and notes beside it, the row of spines or an old photo next to today's view, take it with the church's permission and without flash, never move, open or handle the books yourself, keep security details, children and people's personal details out of the frame, pick a piece count that suits them, and write the note in your own words. You can make a free preview here and decide later whether to send it.

Whatever you send, the most important part is the sentence that sounds like you, written to the person who sat in a cold room above the porch turning pages with a paper slip, writing "late seventeenth century" instead of guessing, so that books chained to a shelf three hundred years ago would still be there, and still be readable, for whoever climbs the stairs next.
