It's a commonplace to state that while other sciences (like biology) may always need the newest books, we mathematicians also use to use older books. While this is a qualitative remark, I would like to get a quantitative result. So what are "old" books still used?

Coming from (algebraic) topology, the first things which come to my mind are the works by Milnor. Frequently used (also as a topic for seminars) are his Characteristic Classes (1974, but based on lectures from 1957), his Morse Theory (1963) and other books and articles by him from the mid sixties.

An older book, which is sometimes used, is Steenrod's The Topology of Fibre Bundles from 1951, but this feels a bit dated already. Books older than that in topology are usually only read for historic reasons.

As I have only very limited experience in other fields (except, perhaps, in algebraic geometry), my question is:

What are the oldest books regularly used in your field (and which don't feel "outdated")?

EGA and SGA, both from the 1960s and 1970s, are very widely used in algebraic geometry. Hartshorne's textbook (first published in 1977) is still the main choice for courses on the theory of schemes.

SGA's are not exactly books, but seminars. – Al-Amrani Oct 12 '13 at 19:53
@Al-Amrani: and yet they were published as books. – Alberto García-Raboso Nov 14 '13 at 22:51

I'm amazed no one has mentioned Hardy and Wright's wonderful Introduction to the Theory of Numbers. It was first published in 1938 and is absolutely delightful.

The most recent (6th) edition includes a chapter on elliptic curves.

share|cite|improve this answer
I remember having read H&W from scratch, a long time ago. Amazingly, E. M. Wright passed away quite recently, in 2005, thus 58 years after G. H. Hardy. – Denis Serre Dec 29 '12 at 8:54
With all due respect, and despite the delightful discussion of some classical topics, this book falls into the "outdated" category in its discussion of virtually anything related to the algebraic side of number theory (setting aside whatever material has been added about elliptic curves in the most recent edition, or perhaps commentary elsewhere in that edition; I have not seen it). As a student years ago, I found it an unpleasant book to read on any "algebraic" topic. – user30180 Dec 29 '12 at 22:30
@ayanta: Well, the new chapter on elliptic curves was written with an eye towards fitting into the style of the rest of the text. (An assertion that I feel that I'm entitled to state as a fact, rather than as an opinion.) So I guess there might be some who would say that the elliptic curves chapter is also "outdated", despite having been written quite recently! But I have to respectively disagree with your opinion of the book, which I feel is a masterpiece. – Joe Silverman Dec 29 '12 at 23:37

I think the absolute record (excluding Euclid) belongs to

E. T. Whittaker G. H. Watson, A course of modern analysis.

According to the Jahrbuch database, the first edition was in 1915. Moreover, this 1915 edition was an extended version of a 1902 book, by Whittaker alone.

The last revision was in 1927. The book is still in print, and widely used, not only by mathematicians but by physicists and engineers. Soon we will celebrate the centenary... It has 1056 citations on Mathscinet, by the way, and 8866 on the Google Scholar !

Perhaps this deserves a Guinnes book of records entry as a "textbook longest continuously in print". And I suppose this is a record not only for math but for all sciences... with the exception of Euclid and Ptolemy, of course:-)

If we include not only textbooks but research monographs there are plenty of other examples, even older ones:

H. F. Baker, Abelian functions, was first published in 1897. Reprinted in 1995, and there is a new Russian translation.

Just out of curiosity, look at its current citation rate in Mathscinet:-)

They also reprinted

H. Schubert, Kalkül der abzählenden Geometrie, 1879, in 1979,

and again you can see from Mathscinet that people are using this.

EDIT: A brief inspection of the most cited (and thus most used) books on Mathscinet shows that a very large proportion of the most cited books are 30-40 years old. Which is easy to explain, by the way. Thus on my opinion, such books do not qualify for this list (unless we want to make it infinite).

EDIT2: Today I accidentally found that 3 of the 4 copies of

G. H. Watson, Treatise on the theory of Bessel functions (first edition, 1922)

are checked out from my university library. Mathscinet shows 1157 citations for the last 2 editions.

Another question is old papers which are still highly sited. A typical life span of a paper is much smaller than that of a book. In the list of 100 most cited papers in 2011, I found only two papers published before 1950 (One by Shannon and another by Leray).

share|cite|improve this answer
I have an electronic copy of the 1996 reissue of Whittaker and Watson's that details its history: first edition 1902, second edition 1915, third edition 1920, fourth edition 1927. Since then, there were 8 reprints (1935, 1940, 1946, 1950, 1952, 1958, 1962 and 1963) and the 1996 reissue. – Alberto García-Raboso Dec 28 '12 at 19:25

Henri Cartan and Samuel Eilenberg published their Homological Algebra in 1956, although it was famously circulated for a long time before that. While that book more or less founded its subject, it is still quite useful.

In fact, this classic book is still used and cited nowadays. The second edition from 1998 is highly recommended. – Martin Brandenburg Jan 2 '13 at 9:26

That depends if you speak of research books or advanced text book. In the second category, I should place

  • Rudin's Real and complex analysis (1966),

  • J.-P. Serre's Cours d'Arithmétique (1970) (hope you will forgive me),

  • Lang's Algebra (1st Edt 1965).

In the first category, I see

  • Kato's Perturbation theory of linear operators (1966),

  • Courant & Hilbert's Methods of Mathematical Physics (1924),

  • Courant & Friedrich's Supersonic Flow and Shock Waves (1948),

  • V. I. Arnold's Mathematical methods of classical mechanics (1974).

I took math 1c-2c I (math for prospective PhD's :-)) from Lang in 1964-65. At the end of the year he had the surviving members of the class pack up envelopes of authors copies of the newly published Algebra to be sent out to his friends/contacts. After an afternoon's work of this he presented each of us with a copy, which I still have on my bookshelf. – Victor Miller Sep 19 '15 at 15:47

If computer science counts as math, then The Art of Computer Programming (first volume published 1968) would be a good example of a text that's still in wide use.

The old edition with a chapter on elimination theory is still a good place to learn the subject. Unfortunately it was eliminated in the later editions. – Abdelmalek Abdesselam Dec 28 '12 at 18:48
Despite its historical importance, this book is not so "Moderne" anymore; its style is "outdated". – user30180 Dec 29 '12 at 22:32
I read the second edition profitably as an undergraduate, though I guess the terminology is outdated. – arsmath Jan 2 '13 at 21:29
I've also used the Elimination Theory chapter of the first editions a lot! – Bruno Jan 10 '13 at 7:59
I believe my copy of this book is the seventh German edition. (I can't check immediately, because it's in my office and I'm at home.) It's title, though, is not "Moderne Algebra" but simply "Algebra". I think it has the material on elimination theory that was mentioned here. – Andreas Blass Apr 20 '13 at 12:19

Abramowitz and Stegun's Handbook of Mathematical Functions (1964) is still used. As the August 2011 Notices article by Boisvert et al. says,

The Handbook remains highly relevant today in spite of its age. In 2009, for example, the Web of Science records more than 2,000 citations to the Handbook. That is more than one published paper every five hours—quite remarkable!

In time it might be superseded by the NIST Handbook of Mathematical Functions (or its online version, the Digital Library of Mathematical Functions), but not yet.

The notes of the 1951-2 Artin-Tate seminar on class field theory (published in 1968, and re-issued in LaTeX form a few years ago with a new Introduction by Tate addressing subsequent developments) remains a fundamental reference in algebraic number theory, despite the abundant supply of more recent references on the subject.

One reason is that it is the only reference outside the original research literature where one can find a complete treatment (with proofs) of certain key aspects of the theory such as the Grunwald-Wang phenomenon and Weil groups for class formations (especially the case of number fields, which lacks a bare-hands construction as for local fields and global function fields). Come to think of it, the general notion of Weil groups for class formations emerged from that seminar...The style of the proofs remains generally quite fresh.

The standard, go to reference in geometric measure theory is still Federer's 1969 classic, Geometric Measure Theory. It is very rarely the first reference one uses since it is rather dense and there are other introductions and expositions, some of them very good.

I'm surprised that nobody has mentioned Serre's Corps locaux (Local Fields), his Cohomologie galoisienne (Galois cohomology) and his Représentations linéaires des groupes finis (Linear representations of finite groups).

If one needs to use tools from classical invariant theory or elimination theory then some books that come to mind are:

and there are quite a few more.

For Salmon's book, the 4th edition of 1885 might be best. Indeed, as I learned from a paper by Macauley, it has a discussion (on p. 87) of Cayley's very general formula for the multivariate resultant as the determinant of a complex (see the book by Gelfand, Kapranov and Zelevinsky for a modern account and a reprint of Cayley's paper).

@Abdelmalek Abdesselam: Can it really be that modern books on computational commutative algebra have not adequately replaced the need to look at a book on "modern higher algebra" from 1876 (or some of the others that you list)? This sounds very surprising. What are examples of things found in such old books that are not available in more recent references? – user30180 Dec 29 '12 at 6:00
@Ayanta: Despite the eloquence of your rethorical question, what you said is simply wrong. For instance anything involving the classical symbolic method in relation with specific invariants coming from elimination theory is not really accounted for nor "adequately replaced" in the recent commutative algebra literature. To form an accurate and informed opinion you need to have a look at the books I mentioned especially Grace and Young if you only have time to look at one. – Abdelmalek Abdesselam Dec 31 '12 at 12:31

Sz. Nagy-Foias: Harmonic Analysis of Operators in Hilbert Space (1970) is a still widely used and lively book (though there is a new updated edition in 2012).

T. Kato's Perturbation Theory book (1967) is also definitely in this category, though there is a 1980 second edition and a 1995 reprint.

Nelson Dunford, Jacob T. Schwartz: Linear Operators (1958,1963, 1971). I still take this book regularly into my hands.

An other reference on differential equations is

J. L. Lions, E. Magenes: Non-Homogeneous Boundary Value Problems, 1972. It is still "the" reference.

András, actually the book by Lions and Magenes is older, in its french edition. I would also add Quelques methodes de resolution des problemes aux limites non lineaires (1969) by J.L. Lions. It seems to me that nobody has mentioned Methods of mathematical Physics by M. Reed and B. Simon (1980) yet, either. Not that old, but will be around for a long while, clearly. Graph Theory by F. Harary (1969) and Algebraic Graph Theory by N. Biggs (1974) are popular classic monographs, too. – Delio Mugnolo Dec 29 '12 at 0:44

Dickson's "History of the Theory of Numbers" is not only old (1919), but it reviews material which is even older. I found it extremely useful when calculating some family Gromov-Witten invariants in a recent paper with Jarek Kedra - while performing the arithmetic manipulations in Section 8, we would have been lost without the wealth of formulae in Dickson. I've no doubt the material appears elsewhere, but Dickson has a comprehensive and carefully historical approach.

Probability Theory, by Feller. Volumes I and II. Oldies but goldies

share|cite|improve this answer

My own field, ergodic theory, is relatively young in that some concepts now regarded as fundamental -- Kolmogorov-Sinai entropy, for example -- were not fully formulated until around 1960. Nonetheless there are a couple of old books still in use and receiving citations:

E. Hopf, Ergodentheorie, 1937;

R. Halmos, Ergodic theory, 1957.

If the 1960s are sufficiently long ago to constitute "old" then there are many old references in probability which remain in heavy use, for example:

P. Billingsley, Convergence of probability measures, 1968;

L. Breiman, Probability, 1968;

and one of the classics of the field:

W. Feller, Introduction to probability theory and its applications, 1950.
