For those of us who think letterforms are art.
See this post on BibliOdyssey.

Thanks peacay, I am in love with your mind.

Penmanship

My own penmanship is terrible but I do admire it as art.
The online library of Rare Books on Calligraphy and Penmanship
hosted by The International Association of Master Penmen,Engrossers and Teachers of Handwriting.
"These books are no longer in print. Preserved in digital format, we offer them here in their entirety for current and future generations of calligraphers, penmen and pen artists. Enjoy."
Note: I wrote to thank them for maintaining this wonderful collection and this is the reply:
"Thanks for letting us know! We seldom hear from people about whether they like it or not, so I appreciate you writing!"

The Pens Excellencie

I used Simple Edition. This edition supplies straightforward jpeg issues of each page of the book in two sizes: 1000-pixel width ('screenshots', if you have your monitor resolution configured to 1024 by 768), and much larger. A navigation menu beneath the images will allow you to toggle between smaller images and enlargements (to zoom, click on the + sign).

Exquisite Handwriting

La Operina is a slim volume of 32 pages. It teaches italic handwriting and is still essential reading. It shows great handwriting on every page. It is more than a set of model sheets, however. It describes Arrighi’s underlying forms and two basic entry movements. It covers the spacing of lines, words and letters. It deals with slant and joins.

Typefaces

From ArtSearch again. A collection of antique typefaces from their manuscripts. These two actually made me gasp.

Torniello

Amphiarea
Vespasiano Amphiarea, "Opera ... nelle quale s'insegna a scrivere...", Venice 1572.
Woodcuts. The horizontal lines help copying, and also emphasize that the letter-height is eight times the diameter of the main lines.
