The TeX Users Group (TUG) offers a selection of Lucida fonts designed by Bigelow & Holmes, with support for both mathematical and text typesetting. TUG provides a set of Lucida fonts in OpenType format, and a slightly different set in Type 1 font format.
By way of additional comparison: the Type 1 fonts are frozen and will not be developed further, while the OpenType fonts continue to be actively maintained and developed. For instance, the OpenType fonts support more languages, with a variety of visual improvements to their glyphs and spacing. Lucida OpenType is also one of the few font sets currently supporting OpenType mathematical typesetting, and (uniquely, to our knowledge) provides a bold math variant. The regular-weight Lucida OpenType math font includes a newly-designed script alphabet.
To order the fonts in either format, please use this online order form for the Lucida fonts. (By the way, other TeX-related items, including software and journal issues, are available through the TUG store.)
Many other Lucida fonts are available directly from B&H, as well as a blog, newsletter, and more.
Sample documents using and describing Lucida (both input and output, both OpenType and Type 1) are available for your perusal.
For questions related to ordering or licensing, please email email@example.com, or contact the TUG office.
For technical support, please use the firstname.lastname@example.org mailing list. It is a public list and you are welcome to join the mailing list or search its public archives. We cannot guarantee support, but we'll do our best.
The Lucida fonts are offered only on condition of your acceptance of the Lucida end-user license for named individuals, or the Lucida site license for use throughout an organization. The fonts are not redistributable, freely or otherwise. To discuss an OEM license, please email us.
Primary thanks to Charles Bigelow and Kris Holmes for generously allowing TUG to offer this to the community—and especially for designing this remarkable typeface in the first place. They have provided some notes on the Lucida font family, and a vastly expanded essay in 2014 on How and Why We Designed Lucida for your typographical pleasure. An extensive interview of Charles Bigelow was conducted by Yue Wang in 2013.
Other individuals who helped prepare the different releases are acknowledged on the corresponding pages; thanks to all.
