Use the "Export list" list function to export all the items from your list - you can save it in several formats: Word, PDF, Excel, RIS, Endnote and .lgn. The .lgn format allows you to save the list in Leganto format and maintains the sections and order of the items - use this if you plan to re-import the list into Leganto.
You can also use "Print list" to save a PDF version of the list as it is shown.
