After creating a site in the site configuration, you can limit to a specific location like main library or branch library. I would like to be able to chose all of our locations but be able to specify a "home" library which would reorder the collection location identical to when you log in to an account. This "home library" would still show all the locations having copies but would reorder them giving a specific location preference. You could also use this to select and display specific hours and info in the library info window. I'm thinking of this for an opac where a patron may or may not be logged in and may be at different library buildings.
