What Counts as a Complete Set

Every page on this site tells you that completeness is the single biggest thing that moves what a law book set is worth. Almost none of them tells you what completeness means. That is a strange gap to leave in the one variable a seller can actually check before picking up the phone, so this page closes it.

Why completeness outruns age

The instinct is that older means more valuable. For law books it is usually the other way round, and the reason is worth understanding because it changes what you should bother checking.

A run of law reports is not a collection of books. It is a single reference tool that happens to be bound in instalments. Its whole purpose is to be there when somebody checks a citation — and a citation lands on one specific volume, not on the set in general. So a gap is not a proportional loss of value. It is a gap in exactly the years somebody might need to look at, and it devalues the volumes either side of it as well as the missing one.

Which is why a smaller complete run is often worth more than a larger broken one. Thirty unbroken years of The Law Reports does the job. Forty years with four missing does not quite, and the next owner knows it.

Edition still matters, and for the big encyclopaedias it matters a great deal. But between two sets of the same title, completeness is usually the one that decides.

The four things people forget

When someone tells us they have a complete set, these are the four that most often turn out not to be in the room. None of them is fatal. All of them are worth knowing about before you describe what you have.

1. The updating apparatus

The big encyclopaedias are not static. Halsbury’s Laws is kept current between reissues by an annual Cumulative Supplement and a monthly Noter-Up service. Halsbury’s Statutes has its own annual supplement and periodic loose-leaf updates. The main volumes plus a current supplement and Noter-Up are worth most — but a full run without them is still worth having valued. The apparatus tells you how current a set is; it does not decide whether it is sellable.

2. The index volumes

Indexes are shelved apart from the run often enough that they get forgotten, and for some titles they matter more than people expect. The English Reports runs to 176 volumes, with two further volumes forming an Index of Cases that brings a full set to 178. That index makes the set considerably more usable, and we factor it in. For the All England Law Reports, the Consolidated Tables and Index volumes add a little when included — and their absence will not stop us buying.

3. The consolidated companions

Some sets have companion volumes that are neither main run nor index. Halsbury’s Statutes has a Consolidated Index, a Citator and a Table of Statutory Instruments; they add value when included but are not essential. Atkin’s Court Forms pairs its 80-plus volumes with a Consolidated Index and Tables, and the main volumes plus those are worth most.

4. The looseleaf service

For a looseleaf work, the binder count tells you very little; the filing tells you everything. Atkin’s is kept current through a quarterly looseleaf updating service, and the Encyclopaedia of Forms and Precedents through its own. A set with recent issues included is worth more — but currency is not essential, and we buy sets with or without the service.

What complete looks like, title by title

The honest version, for the titles we are asked about most. Where we are not certain of a figure we say so rather than round it.

Halsbury’s Laws of England

First published in 1907 and now in its fifth edition. The 4th ran to 56 volumes published between 1973 and 1987, later expanded through selective reissues; the 3rd ran to 43 volumes published 1952–1964. The 5th is still being published and individual volumes are still being reissued, which makes it the highest-value edition to sell. Complete means the main run for that edition, and ideally a current Cumulative Supplement and Noter-Up alongside it.

The English Reports

176 volumes covering case law from 1220 to 1866, published between 1900 and 1932, plus the two-volume Index of Cases that takes a full set to 178. Completeness matters more here than for most sets, and it is the single biggest driver of value for this one. Partial runs are still genuinely worth valuing.

Halsbury’s Statutes

The current 4th edition runs to around fifty volumes published between 1985 and 1992, kept current since by an annual supplement and periodic loose-leaf updates. Earlier editions: the 2nd ran to 33 volumes (1948–1954), the 1st to 20 (1929–1931). A 3rd edition ran between the 2nd and the 4th; we have left its dates out rather than state figures we have not verified.

Atkin’s Court Forms

More than 80 volumes covering over a hundred practice areas, with a Consolidated Index and Tables, kept current by a quarterly looseleaf service. Complete means the main volumes with the index and tables; the service is a bonus rather than a requirement.

Chitty on Contracts

Two volumes — General Principles and Specific Contracts — kept current between editions by regular supplements. The 35th edition, published 2023, is current. A complete two-volume set is worth more than a single volume, and supplements add to the value without being essential. We buy from the 29th edition onward, and older sets case by case.

The White Book

An annual, so completeness works differently: the question is the run of years rather than the run of volumes. Several consecutive years complete with supplements are genuinely useful. A single year on its own is still worth an enquiry, and the Costs & Funding supplement is worth including if you have it.

All England Law Reports

Four bound volumes have typically appeared each year since 1936, so a long-held chambers set can easily run past a hundred volumes. An unbroken run of years is worth more than the same number of volumes with gaps — but gaps are not a dealbreaker. The Reprint covers the earlier period before the main series began; if you have volumes from either or both, the whole shelf gets valued together.

Checking yours in ten minutes

You do not need to catalogue anything, and we would rather you did not try. Three things are enough:

• Photograph the shelves end to end, close enough that the spines are legible. The run reads off the spines faster than off a list.
• Look along the numbers or years for jumps. You are not recording them, just noticing whether the run is broadly unbroken or obviously patchy.
• Check what is sitting beside the run — supplement binders, index volumes, a looseleaf service in its own binders. These are the things that get shelved elsewhere and forgotten.

That is the whole job. Identifying the series, reading the run and spotting what is missing is our part, and it is the part we are actually for. If you are not sure what you are looking at, the law report abbreviations guide will tell you what the spines say.

When a set isn’t complete

This is the part worth saying loudest, because the rest of this page risks talking somebody out of an enquiry they should make.

Gaps change the figure. They do not end the conversation. Every title page on this site says we buy complete and partial sets, and the word partial is doing real work there. A broken run is still a run. It is still worth materially more to a buyer who understands the material than to a general bookshop pricing it per book, and it is still worth more than the skip that most incomplete sets end up in.

The same goes for condition. A set with real damage is worth asking about — we buy damaged books too, and damage changes the number rather than ending the matter.

For scale: a single set normally fetches between £50 and £3,000, occasionally more where the run is complete and the title scarce. Completeness is most of what moves a set along that range. It is not what decides whether you have something worth selling.
