What to Do With Outdated Law Books: Keep, Sell or Recycle

The law changes every year, so somewhere along the shelves of any law library, books are going out of date. Some lose their use the day a new edition arrives, and others are still cited long after they were printed, so the first job is telling the two apart.

Why do law books go out of date?

Most law books state the law as it stands on the day they are printed. When Parliament passes a new Act or a court decides a new case, the book falls behind.

That matters most for practitioner texts, the reference books solicitors and barristers work from. The City Law School's guide to using practitioner texts explains that because they are written for lawyers advising clients, they need to be as up to date as possible. So publishers bring out new editions regularly, and in between they issue supplements or noters-up, smaller works that update the information in the main work.

Some titles are replaced every single year. Archbold, a leading practitioners' book for criminal law, has been published annually since 1992, and Blackstone's Criminal Practice reached its 36th edition with the 2026 volume, having started in 1991. Last year's copy of either is the out-of-date one the moment the new one comes out.

Which law books never go out of date?

Law reports are different. A law report records what a court decided in one case, and why.

Think of a newspaper's sports pages. The league table in last season's paper is out of date by the following weekend, but the match report is still the true account of that match, years later. A law report is the match report. A later case can change the law, but it cannot change what was decided then.

Courts still expect those records to be cited. The Lord Chief Justice's Practice Direction on the citation of authorities, issued in 2012, says that where a judgment is reported in the official Law Reports published by the Incorporated Council of Law Reporting, that report must be cited. If a case is missing from the official Law Reports and appears in the Weekly Law Reports or the All England Law Reports, that report should be cited. So an old volume of those series still holds the version of its cases that a court expects to see.

Age does not stop a report being used, either. The English Reports, which reprint judgments of the higher English courts going back to 1220, are still cited, in the form (1831) 131 ER 305.

So a run of law reports is the part of a law library that does not date. What decides its worth is mostly how complete the run is, and our pages on selling The Law Reports and the All England Law Reports say what to tell us about yours.

Which law books are out of date?

These are the main kinds of out-of-date law book to look for:

• Old editions of practitioner texts and textbooks. Each new edition replaces the last. The City Law School's guide notes, for example, that new editions of Chitty on Contracts come out every few years.
• Annual titles. Every edition before the current year's.
• Looseleaf works whose updates have stopped. A looseleaf is kept current by new pages filed into its binders, so once the subscription ends, the set stops at its last update. Our guide to looseleaf law updates covers those.
• Superseded Halsbury's volumes. Halsbury's Laws replaces individual volumes as the law changes, and its fifth edition replaced the fourth. Our guides to superseded Halsbury's volumes and what an old edition of Halsbury's is worth go through both.
• Procedure texts. The International Law Book Facility, a charity that gives second-hand legal books to not-for-profit organisations, accepts civil and criminal procedure texts only from 2024 onwards, a much tighter cut-off than the ten years it allows most books.

What to do with outdated law books

Work through the shelves in this order, so each book ends up in the right place.

Keep what your work still needs. That means the current editions, and any law reports you still use. An old edition is worth keeping only if your work means looking back at the law as it stood in an earlier year, because an old edition is a record of the law at the date it was printed.

Sell the sets. Out of date and worthless are two different things. A run of law reports, a set of Halsbury's Laws in its fourth or fifth edition and a shelf of practitioner texts can all still be sold as part of a collection. An edition several years behind is worth less than a recent one, because a lawyer working from it needs today's law, but it is still worth asking about. That is what we do, and the next section explains how.

Donate what fits the rules. The International Law Book Facility does not accept books more than ten years old, unless they are the last edition of a text. That exception helps with an old book whose final edition was never replaced. Our guide to donating law books sets out who takes what.

Send rare books to auction. The Law Society's guidance is that legal books are more likely to be valuable if they were printed before 1800, and for those it suggests an auctioneer with experience of selling legal material. If something on your shelves is that old, include it in your photos and say so.

Recycle what is past use. Books that are water-damaged, mouldy or falling apart are for recycling. Check your council's rules for hardbacks first.

For the wider picture, our guide to what to do with old law books sets the options side by side.

Can you sell outdated law books?

Yes, as part of a collection. We buy law book collections and sets: law reports, Halsbury's Laws and Halsbury's Statutes, encyclopaedias of forms and precedents, practitioner texts, journals and rare law books. We don't buy single textbooks.

With practitioner texts, tell us the title and edition of each, because the edition is the first thing that decides what an older text is worth. With law reports, tell us the first and last years and any gaps. You send photos of the shelves, or a list if you have one, and we value the collection for free. If you go ahead, we pack the sets you have chosen to sell straight from the shelves and collect them free from anywhere in the UK.

Where part of a collection has fallen so far behind that it has little resale value, we can talk about collecting it free of charge, so it can leave the shelves with the rest.

Getting a valuation

Photograph the shelves one bay at a time, close enough that the titles, years and editions on the spines can be read, because the years and editions tell us how far behind each book is. Then send the photos through the valuation form or WhatsApp them to 07920 748314, and we will tell you which of the sets, current or out of date, we can buy.
