Einstein's scientific publications are listed below in four tables: journal articles, book chapters, books and authorized translations. Each publication is indexed in the first column by its number in the Schilpp bibliography (Albert Einstein: Philosopher-Scientist, pp. 694–730) and by its article number in Einstein's Collected Papers
Einstein Papers Project
The Einstein Papers Project was established in 1986 to assemble, preserve, translate, and publish papers selected from the literary estate of Albert Einstein and from other collections .Sponsored by the Princeton University Press and the Hebrew University of Jerusalem since its inception, the...

. Complete references for these two bibliographies may be found below in the Bibliography section. The Schilpp numbers are used for cross-referencing in the Notes (the final column of each table), since they cover a greater time period of Einstein's life at present. The English translations of titles are generally taken from the published volumes of the Collected Papers. For some publications, however, such official translations are not available; unofficial translations are indicated with a § superscript. Although the tables are presented in chronological order by default, each table can be re-arranged in alphabetical order for any column by clicking on the arrows at the top of that column. For illustration, to re-order a table by subject—e.g., to group together articles that pertain "General relativity" or "Specific heats"—one need only click on the arrows in the "Classification and Notes" columns. To print out the re-sorted table, the page may be printed directly using the web-browser Print option; the "Printable version" link at the left gives only the default sorting. Collaborative works by Einstein are highlighted in lavender, with the co-author(s) provided in the final column of the table.

Einstein's many non-scientific works are not included here, to limit both the article's focus and size. The division of scientific and non-scientific works follows the Schilpp bibliography, which cites over 130 non-scientific works, often on humanitarian or political topics (pp. 730–746). Five volumes of Einstein's Collected Papers (volumes 1, 5, 8–10) are devoted to his correspondence, much of which is concerned with scientific questions. These letters are likewise not listed here, since they were not prepared for publication.

. Einstein reconciles his and Planck's independent derivations of the blackbody formula E=hν. Planck's derivation of this formula ascribed it to a restriction on the energy changes possible when radiation is produced or absorbed by matter, which implied no restriction on the energies of either matter or radiation. Einstein's 1905 derivation ascribed it to a restriction on the energy of radiation alone, but in this paper, he proposes the modern idea that the energies of both matter and radiation are quantized, which led to his work on quantum specific heats, such as reference #16.

. Second edition of publication #142, with a long appendix covering various topics such as the cosmological implications of general relativity. The appendix was translated by Ernst G. Straus. A "third edition" was published in 1946 by Methuen (London), but it is identical except for a change in pagination. The true third, fourth and fifth editions appeared in 1950, 1953 and 1956, respectively. In the 3rd, Einstein added Appendix II on a generalized theory of gravitation, which was substantially revised for the fifth and final edition.
