I purchased a ream of HP Premium32 printer paper in 2020 and found a couple of sites that offer ruled paper templates. I use the templates to print my own writing paper on a black and white laser printer.

It isn't Clairefontaine, but it is very nice to write on. I highly recommend it.

I'm not sure that I understand your request (alternative as compared to...?), but I have used isbn.nu for many, many years now.

I recently finished The Secret Society of Tea and Treason by India Holton. It's a light-hearted rivals-to-lovers romance with plenty of literary references and innuendos. Plenty of fun.

I'm currently reading Book Reviewing edited by Sylvia Kamerman, with some idea that I could improve how I approach writing book reviews. It's intended for folks writing for journals or newspapers. Because it was published in 1978, the Internet doesn't feature at all. I'm curious how the advice holds up for an Internet-connected world.

I'm interested in what folks are reading, without judgment. You're reading a romance? Cool! Fantasy? Great! True crime? Excellent! Non fiction? Rad!

Are you enjoying it? Would you recommend it? That sort of thing. Just a chill place to learn about what folks are reading.
