Five Essential Reference Books for Rare Book Collectors Compared

Rare book collecting rewards curiosity and punishes guesswork. A bookseller's description, an auction catalogue, the small differences between a first impression and a second: this is a field where details carry the money. Reference books are the cheapest insurance a collector can buy, and the right five will answer most of the questions that come up between browsing and buying.

The titles below do five different jobs — vocabulary, production, identification, valuation and care. They overlap less than you might expect, and none of them replaces another.

1. ABC for Book Collectors by John Carter, revised by Nicolas Barker

This is the one book on the list that every collector should own, and it is the least expensive. It is a glossary — alphabetical, brisk, quietly opinionated — covering the working vocabulary of the trade: collation, conjugate leaves, cancels, foxing, issue, state, half-title, signature marks, and the difference between an edition and an impression. Carter wrote the first version in the early 1950s; Nicolas Barker revised and expanded it in later editions, and the tone has stayed dry and precise throughout.

Read it as a browsing book rather than a manual. When a seller's description mentions a "second issue with a cancel title", you want to know exactly what is being claimed before you decide whether to ask a question. That is the real value here: it turns vague anxiety into specific, answerable queries.

2. A New Introduction to Bibliography by Philip Gaskell

Gaskell covers the ground the ABC cannot: how books were actually made, first by hand and later by machine, and how to describe what you are holding so that another person can verify your description. Imposition, format, paper, watermarks, chain lines, type, binding structures — it is all here, and it has been the standard teaching text on bibliography courses for decades.

It is a dense book, and nobody reads it cover to cover for pleasure. Keep it for the questions that genuinely matter. Was this later impression printed from the same setting of type? Does this gathering look right? Is the paper consistent with the date claimed on the title page? If you are moving from modern first editions towards antiquarian material, Gaskell is the bridge.

3. Collected Books by Allen and Patricia Ahearn

Written by the founders of the firm Quill & Brush, this is the practical identification guide for twentieth-century literary first editions. Entries give the points of issue that distinguish a first printing from later ones: a particular phrase on the copyright page, a jacket price, a stated number line, a textual variant. For collectors of modern fiction it answers the question that matters most — is this actually a first?

Two caveats. The values printed in it reflect the market at the time of publication, so treat them as a yardstick rather than a current offer. And coverage leans towards American and British literary fiction and poetry; genre fiction, children's books and non-fiction are patchier. Use it to identify, then check today's prices elsewhere.

4. Valuing a book: American Book Prices Current and Bookman's Price Index

Two long-running print series still deserve shelf space, even in an age of online auction results. American Book Prices Current records what books actually fetched at auction, year by year, with brief descriptions covering edition, condition and often provenance. Bookman's Price Index indexes the catalogues of antiquarian dealers, so it shows what sellers were asking rather than what buyers paid. The distinction matters: an asking price is an opinion, an auction result is a transaction.

Neither is infallible. A single auction result tells you about one copy on one day. Gather three or four comparable sales — same edition, similar condition, comparable jacket — before forming a view. Condition, edition and dust jacket can move a value by multiples, not percentages. If a book is significant enough to insure, ask a professional valuer to put the figure in writing, and tell your insurer when values change.

5. The Care of Fine Books by Jane Greenfield

Greenfield wrote from the perspective of a working library conservator, and the advice is unglamorous and easy to follow. Stable temperature and moderate humidity matter more than any specific number; damp cellars and hot radiators are the enemies. Beyond that:

• Store most books upright and firmly supported so they do not slump; keep oversize volumes flat.
• Move fragile items into acid-free boxes and slipcases, and use archival polyester covers where an original jacket is crumbling.
• Handle with clean, dry hands, support the spine when opening, and never force a book flat on a table.
• Keep dust, sunlight and food away from the shelves, and check for insects if you store books in a loft or outbuilding.

Resist repairs. Pressure-sensitive tape, rubber bands, household glue and amateur leather dressings do more harm than the damage they are meant to fix, and undoing them is expensive. If a binding is failing or a plate has come loose, speak to a qualified conservator before touching it. For books of real value, professional advice on storage and conservation is worth paying for.

How They Compare — and What to Buy First

• ABC for Book Collectors: vocabulary. Best first purchase; inexpensive and endlessly useful.
• A New Introduction to Bibliography: production and description. Essential for antiquarian work, heavy going for beginners.
• Collected Books: identification of modern first editions. Strong on points of issue, dated on prices.
• American Book Prices Current / Bookman's Price Index: market evidence. Slow to search in print, useful for context.
• The Care of Fine Books: preservation. Short, practical, free of jargon.

A sensible order

1. Buy the ABC first. It cost little and you will use it weekly.
2. Add a conservation guide, so the books you already own survive the next twenty years.
3. Then choose by direction: Ahearn for modern firsts, Gaskell if you are heading towards older material.
4. Leave price records until last. Online auction archives cover much of that ground, and the print series make more sense once you have a collecting focus.

Building the shelf slowly

Reference books go out of date in different ways. Terminology hardly changes at all; market values change constantly; conservation thinking evolves gradually. That is why the glossary and the care manual are the two you will keep longest, and why price guides are best borrowed, subscribed to or checked online rather than accumulated.

A workable habit is to read one entry, one section or one auction record a day and apply it to a book you already own. Look up the collation of something on your shelf. Check whether your copy of a favourite novel really is a first. The collectors who get the most out of this hobby are rarely the ones with the biggest library of books about books — they are the ones who keep looking closely at the books themselves.
