About the practices and the documentation, one of the good idea is take photos, this is a easy and safe way to documentation the collections, but it is not easy to check what object did people saved in the phone or camera. So is a good way practices and take research. Actually there is a simple way to make this way become a good method, put the photos to the computer, pint them out and stick them on the sketch book. It can easily to check, I will use this way next time. Another idea of collection about physical collection. Take the photos or copy about them, make classification for them, then stick the photos and the label (or write the label) on the sketch book. It is a good method to do the physical collection.
