UK TeX FAQ -- question 144

### Parallel setting of text

It's commonly necessary to present text in two languages 'together' on a page, or on opposite pages of a two-page spread. For this to be satisfactory, one also needs some sort of alignment between the two texts.

The parallel package satisfies these needs, permitting typesetting in two columns (not necessarily of the same width) on one page, or on two pages.
