Emigre expands one of my favorite font families with some new faces that are better suited to longer texts:
One area where Mrs Eaves seems less comfortable is in the setting of long texts, particularly in environments such as the interiors of books, magazines, and newspapers. It seems to handle long texts well only if there is ample space. A good example is the book / CD / DVD release The Band: A Musical History published by Capitol Records. Here, Mrs Eaves was given appropriate set width and generous line spacing. In such cases its wide proportions provide a luxurious feel which invites reading. Economy of space was not one of the goals behind the original Mrs Eaves design. With the introduction of Mrs Eaves XL, Licko addresses this issue.
Read the whole thing for an interesting discussion of the development and refinement of this Baskerville revival. Baskerville himself is an interesting character, a master typographer / printer / binder / paper maker whose greatest work was the Baskerville Bible, despite the fact that he was an atheist who saw himself as advancing the cause of rationalism through his type designs.
