Download Annual Edition

From the links below you can download an EPUB or PDF version of Abstract Algebra: Theory and Applications and the corresponding PreTeXt source which is licensed under the GNU Free Documentation License (GFDL).

Understand that EPUB is a superior offline format (as compared with PDF). Fonts, text size, and themes (dark/light) can be configured. This version works well in Apple Books and in Calibre (as cross-platform desktop reading system). Reports of success in Android readers would be welcome.

Note: The 2022 Annual Edition has been finalized. See the note about the various Editions and changes.

The current edition is for the 2022–23 academic year, with only minor modifications to the content from the previous year's edition. It also verifies and updates substantial material about Sage to Version 9.6, available online, and in a special PDF version (see Sage and AATA). The 2009 PDF version is very close to the original text, as first published by PWS Publishing Company in 1994. Since then, the copyright has transferred back to the author, making this open source version possible. (A full copy of the copyright transfer is distributed with the source code in the local subdirectory).

A print-on-demand version is the most affordable way to get a physical copy (hardcover or paperback) of the entire text. However, a PDF version optimized for print (two-sided, no color, etc.) is made available here for your convenience.

Note: A PDF version that includes all the supplemental material about Sage is available for download from the Sage and AATA page.
