Saving Modern Plate Blocks

Probably a dumb question........but when saving modern plate blocks, how are stamps from booklets saved? The booklets do have a plate number on them, but not sure if the entire booklet needs saved, or if you can save a block of stamps from the booklet that includes the plate number.

I know that the H.E. Harris Plate Block album pages only provide spaces for stamps from sheets, and not booklets. But, wasn't sure if that scenario was only unique to Harris albums or ??????????

I'm just saving modern plate blocks as a side project. I figure that as I'm buying new releases via USPS at face value, I might as well buy a few extra stamps to get the block, too. Worst case is that I can always use them for postage later, and not be out anything.

I just save entire booklets.

Scott Regular, Air Post, and Commemorative plate block albums also do not have spaces for booklets. Scott sells separate pages for them and for plate number coils.

I have a small number of older booklets and either do not mount them at all or - as in the case of U.S. War Savings (WS7b and WS8b)- just mount them using matching blank pages.

For my singles collection, I ignore booklets entirely.
