The small plastic binder I use comfortably holds 50 pages, but has room for maybe 25 more (though not 50). You could use several of them for binding together groups of pages like that. Searching around might reveal larger ring binders here if you want larger books.

For larger quantities:

You can use book rings (sold in various sizes) or even binder clips to hold these sheets together in batches, but with the ability to remove them or add sheets later.

File folders might be a useful option too for holding things together in categories.

With some inexpensive book binder's glue and cardboard you could bind together much larger numbers of sheets into custom books for yourself. https://www.youtube.com/watch?v=nivNPCoAHcM is a good basic primer, but you could also do more complicated bindings and covers or have pages bound at FedEx/Kinkos or other higher end professional binders depending on your need and ultimate budget. For this the sky may be the limit, though anything over 1000 pages may be getting awfully bulky.

PVA Glue used in bookbinding, but isn't inexpensive.

• Tacky glue - okay
• rubber cement - not great
• elmer's glue - not great, tears esp. for 2 layers
• Mod podge - pulls nicely and strong
• mod podge hard shell - cracks, not great
• PVA Glue - the best of the group

Recommendations in order: PVA, Tacky Glue, Mod Podge (regular)

Brush on top edge and do two coats. Don't get it down between sheets.

In the early history of printing, books weren't as we see them now, instead they were issued in loose sheets or with temporary stitching allowing the purchaser or retailer to collect, organize, and bind them. This pattern occurs at a time when one would have been thinking about collecting, writing, and organizing one's notes in a commonplace book or other forms. It is likely a pattern that would have influenced this era of note taking practices, especially among the most literate who were purchasing and using books.
