[tselling]

If you used calibre to liberate the books and set the font size you get a lot of p.calibre1, p.calibre2... up to around calibre19 I think. I guess you could add them all the the line. I took a look at the library books to see what they used originally and saw the indent, nonindent, tx, tx1, etc. If your books are without DRM you could also set the default fontsize in Calibre and convert epub to epub for the default 18pt fontsize.
