This is an example of Preservation Services preference from the MIT Energy Lab Reports.  Could serve as a guideline for future projects, esp. research publications:

Ann Marie has reported on the preferred prioritization of items to be sent to Preservation Services then to Document Services.  It is as follows:

For Preservation, our order of preference is based on the amount of time it takes to prep.  Assuming the items have pages in good condition, the order is:

• Loose, unbound pages
• Comb bindings with holes in good condition
• Velobindings (Doc Svcs may prefer velo to comb based on the hole size...)
• Stapled
• Stapled with tape over staples
• Then:  Ratty stuff, including loose pages with lots of paste-ins
