Computer Modern: background and attribution
Donald E. Knuth’s Computer Modern is a reinterpretation of a nineteenth-century Monotype modern-style design. CTAN describes an integrated family spanning roman, sans, monospaced and mathematical resources for TeX. Its later influence includes European Computer Modern and Latin Modern.
Read the publisher’s family page for the source account and the edition currently offered. Keep a family name distinct from its particular release, width or optical branch.
Forms, styles and what to inspect
The base distribution uses METAFONT source, with Type 1 versions available through other distributions. A source package, an outline font and a TeX support workflow are different resources. The package’s Knuth License should be read for the exact distribution.
Use the original publisher specimen to inspect those features. An alternative can share a broad role without having the same letter shapes, metrics or character coverage.
Try it in a real layout
Compare a prose paragraph and a mathematical expression in the target TeX workflow. Source Serif 4 and Lora are independent text-serif comparisons, not replacements for Computer Modern’s coordinated mathematics system. Keep text and mathematics requirements together when choosing a document setup.
For independent comparisons, try Source Serif 4 and Lora. Use the same wording and approximate output size. The related style guide provides broader design context.
Official preview and font resources
Use CTAN to try the original and investigate the files, styles and terms for your intended workflow. This site does not distribute or serve Computer Modern font software.
The editable alternatives here have their own source profiles and included licenses. For the difference between a font file and copied characters, read Unicode text versus fonts.
Your questions, answered.

Does this page supply a Computer Modern font download?
No. Follow the publisher source to investigate the original resources and their terms.
Are the alternative fonts exact replacements?
No. Compare letterforms, spacing, script coverage and layout before choosing an independent design.
