[Avodah] Printing email to read on Shabbos

:> One could argue that there's a serious risk of picking up a pen to make
:> notes.

To which R' Moshe Y. Gluck responded:
: One can prohibit - based on that argument - all Torah learning from a text
: on Shabbos.

I clearly recall learning that galley proofs are muktza  as there's a
serious risk of picking up a pen to make corrections.

One could argue that the whole point of reading galley proofs and
email threads is to "make notes" which may not be the case when
learning from a text on Shabbos.

On second thought, if that's your style of learning (to make notes
about everything) or you're trying to put together a "pshetl" then
maybe you do have a problem...

I quick look at the SA:

- 307:12-15. There's a problem reading lists of invitees lest one
erase. No mention of writing, interestingly enough. Reading books (as
opposed to seforim) is forbidden, but not because of "editing".
Reading snail-mail is problematic, but not because of fear-of-editing.

- 339:4. Court cases are forbidden because one may come to write.

- 340: 5. One may make a line with ones fingernail on a sefer. MB:
Only a line as a reminder OR TO MARK AN ERROR, but not a letter - and
only with ones fingernail, not with an object. Caveat: only parchment;
paper may be forbidden because the mark becomes permanent. (MB,
Achronim.)

Nothing conclusive, from what I can tell...
